Thanks for all the advice. I did end up taking to an amp tech and it turned out to be the diode rectifier bridge. he replaced it and all is well! Going to take out that 11amp circuit breaker out and put in a fuse holder with 4.5a fuses instead.

Q & A / Re: Vintage restoration of 200S
« Last post by GrannyGremlin on March 01, 2017, 08:37:53 pm »
the graphics are all faded off the chassis and I don't know where or if I can get that going or not for this amp, so any ideas are appreciated.

In such situations I usually print out the graphics on a transparency (like for overhead projectors), and mount it using the pot, jack, switch and existing screws to hold it on.  It's best if you print it mirror image so the ink is against the chassis protected by the back side of the transparency and doesn't just get worn off again.

... but I'd be keeping it vs selling, so...

Just found this posting and requested a sample of the p4540. Looks to be very close to what Traynor is using and might be a good match to the older Sunn cloth. Thanks for the research into this!

The band Diazepam used this same Sunn 200s on both albums, among other great amps.  I started cleaning it up, was a bit dusty, and inside I found that all components are original as well as the tubes except for the rec tube.  Even better I have a mess of unused vintage correct caps, the cornnell dublier type.  I was thinking about modding this amp until that point but think I ought to keep it original.  I will get pics up soon.  I don't plan on keeping this amp either.  Just too damn clean for me.  Here is the deal... the graphics are all faded off the chassis and I don't know where or if I can get that going or not for this amp, so any ideas are appreciated.

Are you trying to sell it? If so, how much do you want for it? Come up with a price and I can move this to the Classified section.

I agree with Issac. Your amp is drawing too much current and the circuit breaker is doing what it's supposed to do.....shut the amp down. There is no way the breaker is 11 amps. You need to take your amp to a knowledgeable tech to have it properly repaired. Installing an over-sized breaker increases the chance that you may be creating more damage. The warning notice "no user-serviceable parts" is not a joke!

My first thought was, what makes you think that the circuit breaker is faulty? Sounds to me as though it's doing exactly what it's supposed to do.

My next thought was, no way that's an 11 amp breaker. Putting in too large a breaker will allow the amp to draw too much current, potentially burning things up. From what I can find online, 4.5 amps looks right.

It sounds to me as though this problem is beyond your ability. Something in the amp is drawing too much current and popping your circuit breaker. No way to know for sure what that is without a closer look. If you're lucky, it's just a power supply cap, and is easily replaceable. Could be any number of other things, though.

Q & A / Silverface Concert Lead Circuit Breaker Tripping!
« Last post by georgec64 on February 20, 2017, 07:13:35 pm »
Greetings friends,

I've been having a problem with my Silverface Concert Lead. Played the amp at a moderate volume and it turned off—no red light or anything. Opened it up and noticed a faulty circuit breaker. It looked like on the top of the red button of the circuit breaker was the number 11, which I assumed meant an 11 amp circuit breaker.

I bought one online and put it in. Now, the amp powers on for a few seconds then trips the breaker. Perhaps my amp is drawing too much power?? Except the weird thing is that I have looked at friend's silver faces and the number on the circuit breaker has been different on each one! Mine says 11, though I've seen amps with 12 and 13 amp circuit breakers.

Will probably take this amp in, unless anyone has experienced a similar problem and has succeeded in fixing it? Amp technicians tend to steer away from concert leads, so if there's any way i can fix this that's be very kool. Thanks

Classified / Sunn 415M 4x15 Bass Cabinet For Sale
« Last post by jayochs on February 13, 2017, 10:09:40 am »
Hey guys, new here.  Looking to put out some feelers for a 415M I've got that I'm looking to sell.  I'm located on the shore of NJ, and I'd probably only do local pickup because this thing weighs like 130 pounds, and shipping that is a damn nightmare...besides the fact it's in my basement and I need to find someone to help me get it out, anyway! lol.

either way, I've had it for about 12 years now, and I've brought it to a few gigs when I played live from 2010 and 2011, but other than that, it's been in my basement for years.  Sounds good, speakers are original and work fine, in decent shape for a 70's cabinet, and has all 4 casters on it.  Looking to get rid of it mainly because I want something much smaller (2x10 or 4x10) that has a horn so I can get some honky mid-high range sounds out of it.

I run it w/ a GK Backline 600 and it's LOUD as hell.  and idk why people say these things have no low end, because I find this thing to have tons..then again, I never owned a 4x10 so i don't know.

either way, in looking to sell it, I'd probably be looking around $600 or so.  What's everyone's thoughts?  And is anyone interested?

Thanks!
