Yw. I got mine from mesa . call Chris or Rich. He will fix you up. Get the cap as well with it. 100uf 6.3volt. Radial cap. He'll know. No. Don't replace the other at this time. One thing I forgot to ask, is the pilot light blue or red? Blue is older first version, red is second version . little...

Yes. I replaced every electrolytic cap in it. Filter caps.....etc two years ago. Yes its still original. It has had some repairing done to it over the years but no mods. Thanks, Jim

Greetings. Those two black components are called LDR's. ( light dependent resistors).Or optocoupler . One for each channel. They act as a switch. Inside those little black components, One side has a led light and the other a panel. They are polarized. They are for the Half Drive switching...

A major increase in volume. Tone? Eh. There is a long story with my amp.

Hello, you are one of the lucky to not have issues with PT connector. What is it that you would like? I can help you with values of caps and such. Jim

Greetings everyone! Ya know, I've reached a pinnacle in my life where I would like to know and understand some things before I leave this ******, broken planet soon. One in particular is that I purchased a factory DRG C+ in 1984. Suddenly my Simul Class switch when engaged kicks ***! Never has...

What are you interested in doing? Maybe I can help.

Yw! just spent the last 20 minutes or so studying your gut shot. Since V4 is out of play, I'm assuming that V3, both sides, are your lead channel. And I really can't tell by the picture that if that orange drop with those two caps with silicone on them are going to the plate of V3 ( towards...

Is it the gut shot with no verb? If so, that appears to be a RP10 preamp board. And I have zero experience with them. That sux because I love to help ppl. Its hard to see those caps near that orange drop. For what its worth, look for a plate resistor, 270k (red,purple, yellow color bands) and...

I'll do it when I'm on laptop. What areas do you want me to focus on? Is there a limit to how many picts I can upload? If we have the exact amp, I can tell you what caps need to be removed and/ or changed if you open your chassis.

I'm on my Kindle now. None on this gadget. My laptop has a folder full of them . when on LT , do I open folder and select picts to upload? It might be easier if we were on a different platform. Like messenger or something. If we have the exact amp, I can tell you exactly what to look for inside...

Yes, I have lots of gut shots of my amp but don't know how to upload them here. Make sure that we are on same page. I have the RP11A preamp board.

Thanx for rep!y! Going down in resistance, how would that affect presence? Thank you, Jim. Side note. I have all of the bright reduction mods from factory.1000pf in parallel with 270k on V4A. 10pf across 3.3 meg. BB claims that is should be 20pf for Simuls. Blessings. Jim

Forgive me for chiming in . My MK II DRG C+ has a 3.3k on presence. It came that way from factory. Should I change it to 1.5k? Not sure if this is relevant but my preampy is a RP11a. Thanks.

It does seem confusing. What part or parts don't you understand? Ill try to detail it better for ya my brother. Blessings.

Glad that I had some entertainment with this post. lol. Blessings.

Ok, the other day I was playing my DRG C+. It sounded ok. Occasionally, with amp on, I'll unplug input and get a pencil and very gently tap on preamp tubes to check for microphonics and other noises. I also turned all of the front knobs just to loosen things up. Put settings back exactly where...

Hello. I've had the opportunity to only try version one, which I've owned since the mid 90's. I don't have a triaxis tho. I slave my C+ to it. No, it's never been noisy. Of course if you crank up the levels all of the way, with no input, you will hear a very slight hiss. And of course certain...

Thanks for the schematic. A short while ago I had a chat with Mike B. about my C+ DRG. I was asking him why my amp still had C21 , 1000pf, and C10 was a 10 pf while the schematics said otherwise. He told me that those caps are a bright reduction mod in earlier C+'s. Mine still has C25, 500pf...

Thanks for the reply and info and link! I'll give it a good once over! :) Blessings, Jim
