Agreed on Guitar Electronics. More experienced pros in one shop. That's where my gear goes now.

Thad got my '65 Strat back into top playing condition right before he moved south. He did an excellent job and I would have been a repeat customer if he had stayed. Then again, that's how I found Guitar Electronics so it's all good. :)

Oh no not another DRRI thread! :)

I just got mine yesterday and couldn't help myself, had to share my excitement! This is exactly what I was looking for, the tone that comes out of this thing is something else! I wasn't sure what to expect... but the combination of a DRRI and the Fralin Blues Specials is tone heaven for me!

Image

Those two together are getting way too much attention... my 335 sounds amazing thru the DRRI too! couldn't be happier!

Image

I do have a question... this was brand new still in box amp, do I need to worry about breaking in the speaker? I notice a slight rattle, could be tube rattle at higher volume, specially when playing low notes, is that normal?


Congrats man! The DRRI is a great sounding amp.

I don't plan to change the rest of the tubes, just need to get rid of this tube rattle, which I believe is coming from the rectifier. The 6v6 in my DRRI are EH, and I'm very pleased with the way the amp sounds, no need to ruin a good thing :)

Shall I just order a JJ rectifier and call it a day? Any other parts I need to worry about? Just like to keep extras around in case... My Mesa Lonestar Special is known for going thru rectifiers and fuses.

How do I check the bias? What tools are needed? I don't usually work on my amps, just replace tubes and speakers, I don't bother with the other stuff...


Eurotubes has a video and sells the Bias Probe. It's not a huge investment. It's a good idea to check the bias once in a while and a must if you change power tubes unless you amp is cathode biased.

It's also a good idea to buy a really good volt meter....a Fluke is what I use,expensive but worth it.

Unless you're doing repair for a living, a Fluke as nice as they are really isn't necessary. Most of the digital volt meters around today are pretty accurate. If you're into serious amp building and troubleshooting I'd highly recommend a Fluke. For biasing, I'd just get a bias probe and meter.

For general use, I keep a cheepie DVM close at hand (I'll even take it along when gigging or jamming "just in case"). For serious bench work I'll drag out my GI-issue TS-352/U VTVM. It's a bulky dinosaur (like me, ha ha!) but it gets the job done.

I do agree with y'all about the DVMs,and I do use the cheap one I have,but it's nice that the utility I work for has provided a top end Fluke that I can use whenever to play with the added bells and whistles. :)
I do own an older Fluke 73,I think the model is,and it is fine.

I ended up ordering the Weber Bias Rite from Eurotubes and their retube kit, just to see if I can get rid of some of these rattles and buzzes... it was very easy to bias the amp, mine was around 20 mA from the factory.

No luck getting rid of the rattles, once the amp is at 6 or higher I still get tube rattle, even with the new ones in there, but now it seems to only happen when playing low notes on E and A... maybe something else is rattling, who knows, I won't be messing with it anymore, waiting for a replacement to get here so I can swap it out. I love the tone but I'm tired of hearing these rattles when the amp is turned up! Anyone tried the tube damper rings from Eurotubes? Would it help?

In the process of replacing tubes it looks like the original V1 became microphonic! I put the original tubes back when I decided I was taking it back for another one, that's when I noticed it...

Are you positive its tube rattle and not something in the room? Did you try moving the amp to a different room? Dampers can work, they helped my HRDlx a lot.

Yeah I'm sure, I stood behind the amp and can hear it there. The tube rattle I was getting before was the rectifier, specially when playing a G, that's gone now. I think what I'm getting now are still cab rattle, or somewhere in the chassis, only happens on low notes with volume at 6 and guitar turned up. Just don't want to mess with it anymore... it's weird, when I put the JJ kit in, I did notice a slight tube rattle, but now it moved to D instead of G that I was getting with the original rectifier.

These rattles are not loud and I'm sure I wouldn't hear them if I was playing a gig somewhere... but at home, anytime I have the volume set at 6 or higher I hear it! and that's where I get the best tone! :( of course things get much worse as I turn it up even more. It could just be the nature of this combo, with the speaker so close to everything... but I don't have that problem with my other combo amps, usually the house rattles before the amp! :)

Arjay... Have you ever been to Music Brokers in Phoenix at Central Ave just south of Camelback ?? They have a bunch of vintage fender amps there...


No I never have, CB. But I've read you and others here make mention of them several times. If I ever get up to the "big city" again I'll definitely check them out. The few times I've been to Phoenix I stopped by the GC in Goodyear and another place in Peoria (forget the name -- "The Bass Place"?). My luthier used to own Precision Guitars up there but he sold the shop about five years ago to move down here. He's a Border Patrol agent now (!).

Thanks for the tip.

Arjay

So that's where Thad Robosson ended up. The Border Patrol's gain is Phoenix's loss. Precision Guitar was a fine shop.

Precision is still a fine shop IMO. What didn't you like after Thad left?

I haven't been back. Precision's Web site disappeared right after Thad moved and I lost touch.

I had a Hot Rod Deluxe that started getting flaky around that time, did a Google search for authorized Fender amp repair and found Guitar Electronics. They have been shop of choice the past 5 years.

Update on my DRRI... to those who recommended the Tung-Sol reissue (6V6), thank you!! Just got 'em today and replaced the stock ones, much better! I can't really describe it but everything is so much clearer and crisper now. I tried the JJs 6V6 and didnt really like them, much happier with the Tung-Sols. I do have the JJs in the preamp tho.

Just to refresh everyone's memory, this is my 2nd DRRI, the first one had a nasty rattle, the replacement, now with the Tung-Sol, doesnt rattle. However, the new one seems to have a different problem, it does tend to get "farty" at higher volumes when playing low notes, didn't experience that with the first one, just nice tight bass... this problem exists with all the tubes I've tried. I actually liked the way the first one sounded, except it had that annoying rattle. I don't wanna take it back and try a 3rd one! What are my options? Replace speaker or is something else causing this fartiness??

The salesman even recommended going with a Vibrolux but I prefer the sound of 6V6s and the DRRI.

Your thoughts?
