want 2 Rok JM signature tone board layout

[ToneMerc]

Okay I will use this board for my drill pattern.

Are those Dale 0708J 100K plate load resistors NOS? Is it 1W or 1/2w?

No, being made in 2007 they are not new old stock as the amp was built in 2009. They are Vishay Dale RN65D which of course is 1/2W, easily found at Mouser.

Ah these are the rn65d. I bought them yesterday but haven't arrived yet

I could not find anything with the reference 0708J which is why I was confused

Thanks for clarifying

0708J is the date code: 2007, 8th week, JAN or Joint Army Navy

That is very insightful

Thanks again

Any recommendation for a NOS MF 220K for the PI

Why continuously fret over what "old" resistor should go in what position. Like I said before there at lot's of MF resistors, choose your tolerance and pick one.

I think that you worrying far too much about what resistors to use, just from your questions it appears that you have very little experience with component electronics and that most likely translates into very little assembly experience as well. This by any means is not a bad thing, just be advised that slick NOS parts selection alone does not make a successful build assembly.

I appreciate the feedback TM

You are absolutely right, up until now I only worried about (1) curcuits: schematic and layout, (2) speaker cabinet: wood, size, open/closed back and speakers

Now for the first time I am looking into BOMs and parts (we all have to start from somewhere)

I have no assembly experience and don't plan to start yet putting it together and hence why I hired a trustworthy qualified amp tech (who has been taking care of my amps and vintage pedals) to bring my amp into life

I am very meticulous with my gear (pedals, cables, pick ups, strings, woods, etc.) so Inspite of the lack of experience I want to make sure only hand picked premium parts will go into my built and I am relying a lot on the forum for that

I would like to thank you again for all the help and guidance so far

Hi Mark,

I know it has been over three years since you touched this amp: I have a few questions, if you remember.

- Am I correct in assuming you wound up with about 460V on the plates?

- I'm curious about the Cut Control. I see TR calls it Contour.
- Did you find it useful?
- And did you wire it so that the bright end was with the knob on 10, or 1?

- Did you use 6L6GC for the outputs, or something else?


Thanks, Mark,
Lou

Hi,

Like I told you over the phone....it does not work like that.


Build an amp, and when you play it the first time...you will be disappointed. It is how this goes. Put time into tweaking, and I mean several years, decades even, and you will master it. There are no short cuts that I am aware of. If you find the short cuts, please let me know.

Lou, I don't have a voltage chart available but I'm sure it was around 450-460vdc on the plates. The cut control is something I put in a lot of builds because I like adding in some darker tone. It's wired to the wiper first so I believe it gets darker clock wise.

[Bombacaototal]

Thanks again Jelle for all the help and patience with my questions

I absolutely understand your point and being completely honest I don't expect to get it right at the first time. I just figured it would be much easier to tweak something that is built already than building from scratch;-)

I agree with that., It took 20 different mid caps before i settled on my 102 holy grail build. and that was just one part

When trying different values like this are you going for alligator clips?

Just put of curiosity which value did you settle on?

You are missing the point. Sometimes it takes several different specimens to find the right cap. Or the right resistor.

It is not about the value. At all.
