Traynor Bassmaster YBA-1A Help w/ 3 Prong Cord Plz! (pics)

[Jerry2013]

Got my Traynor YBA-1a Bassmaster recapped. Now I need to figure out , with your help please, how to install the 3 prong cord. I have searched on the web till Im blue in the face for pics on exactly what to do.
I have too many projects to take this to a tech- cannot afford it, and Im not literate with schematics.
If someone could draw me a diagram , or give very simple to understand instructions on exactly what wires to cut and hook up where I would be forever in your debt.
If not, I guess I'll just ground the green wire on the new 3 prong cord to chassis, and hook up the black to the old cut black and the white to the old cut white and hope for the best. I've already removed the 'Death Cap'.
I'll be pretty much be done then on this amp, then I expect to put in screen grid resistors, as there are none stock on the amp, and I'll ask about that next. Thanks!;

I'm from from the old school, we were taught even the most basic technical concepts before we ever worked around live circuits or even poked around in a non-energized chassis period. It's makes me cringe when read pots like this, nevertheless........................

Well it looks like it needs to be updated to modern electrical safety standards as well. It's kind of silly to change it to a 3 prong cord and leave the fuse on the neutral.

leave the fuse on neutral? What does that mean?
What would be wrong with just connecting the new std. American cord white wire to the old white, the new black to the old black, and grounding the green wire? I appreciate your concern, and I appreciate you trying to help, but I gotta do what I gotta do. As long as the 3 prong cord is installed adequately, and I have done the cap job right, and observed and i don't take anything lightly,then I'm good.
The instructions links you gave I don't understand- i need something simple, and specific for this amp- theres also a red wire running from the" ring" of the fuse that is not mentioned in the link. A drawing or a point by point step by step instruction based on what I have in the pictures is what I'm looking for.
Like I said, i can't read a schematic. Ive got some really nice expensive old amps I'll need to fix up pretty much by looking at pictures I can find on the internet for and other pertinant info about the amps, asking questions about cap valaes where I'm not sure and not by reading the schematic.

The good news is that out of about 10 old amps Im recapping, this is one of only a few that have not already had the three prong cord installed by someone. besides the following amps-Ive got an old Sunn, and old Valco, and an old Kustom . one amp I will not try ot do myself is my nice old 73 pt. to0 point Superlead.;

It means, with all due respect, that you have a fundamental lack of understanding of the most basic of electronic concepts that put you at personal risk as well as potential risk of fire.

Like you said, you gotta do what you gotta do and no one can make that choice but you but you are asking people here for help and the very nature of your inquiry throws up a big flag. If someone gives you advice that you fail to follow or understand, you are unwittingly transferring that risk to them, and that is unfair.

Successfully working and even building an amplifier should not be relegated to "soldering by numbers". People do this all the time but ultimately if you lack the depth to understand and follow a schematic, be able to identify the parts and their basic function, you put yourself and any users of your work at risk of personal harm and even death.

You're not going to ingratiate yourself with this community if you blow off advice that is being offered that can keep you alive.

Just sayin' dude.

I second what colossal said.

Okay, I see,. let me ask this then, and I'll leave it at that;
Would it be safe to go ahead and connect the new cord to where the old cord was, being certain of properly connecting the wires properly, and just grounding the green cord?
Would anyone have a picture of a detailed picture of a Bassmaster like mine that has had the 3 prong cord installed? Ive had to learn a lot of stuff just by pictures...sometimes anyone would, like where there is apparently no schematic available for my Alamo Fury amp. I would have done it from a picture, but couldn't find any on the net.
Also, a drawing would be perfect... ya can't go wrong with a drawing of exactly what to do . That is safe . It all boils down to trust. i trust you guys. I'm not doing anything invasive here, changing the circuit or anything. I'm not sure if anyone here would be willing to spend the time on a drawing for me.

Thanks. I'll study those and see if I can determine something. Maybe post a pic. I also have a variac I'll need to ask you guys how to use to bring these amps up to power after I'm done with 'em.
heh, think of me as a Robinson Crusoe, alone on a desert island trying to survive, working with only what is provided ...thats essentially what I am.
I'll tell you this right now. I do not have a technical mind.Couldnt even pass basic business math in college. Its not like i don't know tons about amps, which tone caps are good and such.. just not the technical side, but enough about me.

^^^ +100 what Colossal said

I wasn't even going to reply to this thread, and I don't mean to "pile on", but working on amps is far too dangerous if you don't know what you're doing. It ain't a color-by-numbers undertaking ...... unless you have a death-wish and want a visit from the undertaker.

That photo scares the hell out of me. The lead dress (1st photo, Traynor) on those caps is unfit for duty IMO.

Yeah, now that you mention it, I think it'd be a good idea to goop the caps down onto a breadboard and goop that onto the chassis. it was all done properly by me as far as cap values and polarity, and I'll make certian there is no chance of anything shorting out.

yes, I think we should leave this be now, i get your point everyone, I do, so if anyone can get me a drawing or a pic, other than that, I won't post another such inquiry, just asking about maybe cap value questions as if in a vacuum.

Jerry,

I wasn't trying to jump on you, I hope you understand that. The process of learning should be fun. If you don't get something posted on a referenced link, google it again, and read something else. Do this over and over again until you get it. You will be stoked and fired up to learn more when you do get it. This forum is a library of information and all you need to do is lose about a year's worth of sleep sucking it dry. That is hugely rewarding in itself. There are some great, great people here that have seen and done it all; people I greatly admire. The journey is in the way, not the destination.

What we want you and anyone else starting out to do is be safe, not take unnecessary chances, and do the work yourself. You gotta invest. When people here see that, they will be more than willing to help you out. Lately there has been an influx of people just wanting a short answer and obviously not willing to invest any personal time. People don't get to drink from the well without some investment.

Stay safe!

Here is a quick reference to installing a 3 wire cord. Look for "make it safe."
http://www.rru.com/~meo/Guitar/Amps/Kalamazoo/
What I'd add is that you probably don't have a chassis ground lug where you can solder the green wire. Drill a hole for a dedicated bolt.

[selloutrr]

Holy crap Jerry you removed the filter cap cans and mounting bracket. Those caps start shaking around from the speaker vibration and the leads short on the chassis... BOOM!!! That voltage travels to the path of least resistance. You wire up your power cord wrong and not only will you fry your amp to shit but you could very easily get a shock that could give you a stroke, stop your heart, or kill you or whoever is playing your amp.

I'm scared!!!

Now that you have done a cap job.. Let me guess.. How do I bias an amp...

STOP!!! It's great you have an interest but study before you break out the soldering iron. As all these knowledgable builders have pointed out its not a joke! It's not a matter of if just when you or someone who uses your amp gets hurt. The best part.. You will be liable, which means it all comes down on you. If they aren't dead.. Which means jail time for you if they are. They sew you for all that you have. But, hey. Go ahead and cut corners and poke around in high voltage.

Safety issues aside, I'm afraid that there is more money being lost than saved here.

[vibratoking]

This is a great thread on "how not to do it".

[Jerry2013]

Point well taken everyone. Thanks for your interest. It will be done properly. I am *not taking this lightly.I know about 'gooping' the caps for vibration and being careful about leads shorting out. The kinds of cap jobs where one disconnects the old can caps and relocates new
Electrolytic filter caps caps underneath on the chassis are very common .Also know to be 100% certain about the cord before I power it up on the variac.
I wasnt aware the amp would positively have to be rebiased after the cap job. Why?. I have done cap jobs before and as long as nothing is redplating and the trannys are cool to the touch I see no absolute need. Thats something i wouldnt try.


BTW, I was big into vintage a tube audio way before most others were and everything became so popular and skyrocketed in price and became impossible to find. had some of the best vintage tube hi-fi amps in the world pass through my hands.
I was poking around in an old 'real' pure class A theatre 40's theatre tube amp and got a shock that made me sick for a week. I was young and strong at the time; now that shock would kill me. I'm sure it knocked a few years off my life (heart scar tissue), but live and learn. That kind of shock won't happen to me or anyone else on any of my amps again..Ever!
