Bruno schematic

[drz400]

Maybe he made this one? This one came across my bench. luckily the guy could still return it. I had him send it back!!!

That cant be for real is it? There has to be some weird story behind it. I cant believe someone does that kind of work would bother to make a PCB for a relay

Looks like a Dumble type?

What's under the masking tape between the two pairs of metal oxide resistors standing on their leads?

[slajeune]

Well,

here is another example of Bruno work:

what the heck is wrong with that p2p site? even the last site that guy had was problematic.

[David Root]

Didn't work for me either.

I typed in p2p-amps.com and scrolled though most of the amps until I came to Bruno Leadman...I'm assuming that is what the link is for, and it's a gut shot of a crummy looking amp chassis.

I went to the site and found a Bruno Leadman
looks kind of scary to me
The twisted heater wires are kind of funny, why bother
Most of the builds I have seen here look a lot cleaner, but I have seen some more expensive more well known amps that look even worse

It seems that everytime someone posts a pic of his "handywork" some minion comes back with.."that is a prototype" I guess they are all prototypes!

[ampdoc1]

Man,

I can't believe anyone would prototype like that! The chances of hum, noise, and buzzes from the build quality alone, seems like it would decrease the likelihood of turning out something listenable. My builds are not Allynmey quality, but I know what straight lines and right angles are!

I love this pic! It makes my builds look decent.

Hey Guys,

Well, the Bruno UG30 is in Germ's hands now. I met him a few days ago; real nice guy and he has some very cool amps in the works, so be sure to check out his stuff if you ever get the chance.

I guess he can comment on the Bruno build quality from seeing my amp. In appearance, it's not too bad, although I could point out a couple of flaws that come to mind. I should have taken some pictures before I dropped it off with Germ. Maybe I'll still do that when I get it back if anyone is interested to see it.

Well....
Better than the others but it certainly doesnt look like planning or neatness are his forté.

Hi guys
With all due respect guys, in the end, Bruno's amps are the ones that have a name, are the ones reviewed by major magazines with awards, are the ones that still have resale value in the used market and are coveted by many players. If the amp is built safely, does not hum and it sounds good, perfectly parallel and perpendicular wires IMHO are just a little icing on the cake and not a necessity. If the circuit doesn't require it, frankly who cares.
Regards
PS
I am not associated with Bruno in any way shape or form. Just another opinion.
Peace

Can't help but reply to this one.
Are you kidding?
Anything you construct, build, etc., especially an electronic device, such as a guitar amplifier, requires attention to detail, neatness, economy of function and layout, and thoughtful planning in all areas of design and assembly. Frankly, this is "Engineering 101" for those of you that may not have a technical background.
Multiple problems have been identified in amplifier designs which LACK this attention to detail, e.g. parasitic oscillations, cold solder joints, broken wires due to excessive motion of wires/parts from vibration, hum, heat damage to components, and on and on and on...
Just as an example, since we're critically analyzing (not dissing, so please, no one get your feelings hurt - don't forget, I own a Bruno), look carefully at the photos Germ provided inside the UG30 chassis. Note that there is a green wire from one of the input jacks leading to the circiut board which has been soldered in place very taut, without any slack. I have always known that this is a potential problem because any jolt, or maybe even vibration from normal use could compromise this connection over time. That's why amp builders don't ordinarily secure connections in that manner when reaching from chassis to board, one board to another, etc. Well, TB did that, and it's a mistake.
Furthermore, although sloppiness in wiring and layout does not necessarily negate other positive attributes an amplifier may have, it can certainly be used as an indicater of overall build quality. This correlation has been noted many, many times. One glaring example is the early silverface Fender amplifier, which suffered so much from poor wiring, excess lead dress, and bad routing that the amps began to have circuit function maladies directly related to "sloppy" assembly.
