Before we played on Friday I was warming up and just doing a very basic sound check into my 65 TRRI. When I was playing the amp would sort of muffle on its own and the volume would come and go. By the time we started playing I was louder and didn't have much of a problem. To try and eliminate what was wrong with it I went directly from my guitar to the amp with a couple different cables, it didn't change. I haven't plugged it in yet, but I was wondering if anyone here ever had a similar problem, and what it was?

Thanks

I've got the same amp and have been having a similar issue. Mine would go from a moderate volume to sounding like it was on 10. Sounded great but my bandmates didn't appreciate it too much.

I handed it over to my repair guy who's a tube amp wiz. I'll let you know what he says. The problems aren't identical but sound similar.

Oh, I see your problem: TRRI....

at least I have a good excuse - only cost $250

now play nice, Brad

although, I have always been a proponent of:
" why get a reissue when you can get a late 60's/early 70's one for much less money, and have a good tech go over it and blackface it, and still have a couple hundred left over from what the new RI would have cost!"

After I have my "fire sale" I'll be giving Brad a call

you and me both, brother. you and me both ..... I have been wanting to pull the trigger for so long, but the wife will have my head unless I flip something for it.

I'm just funnin. I like to bug people with RI Fenders. They're ok, seriously, but really my general and more real point is that I think everyone who owns a RI Fender should sell it and get a REAL Fender from the late '60s or '70s. I'd take a total beater '72 Twin and spend a few bills or hours getting it all up to snuff before I'd try to deal with the servicing nightmares of a RI. They're just SO hard to work on compared to a real Fender amp. And pretty much everyone here on this forum needs to get inside their Fender amps and change a few things if they want to get them to do all this sweet Jerry tone stuff. It's just no fun on a RI Fender circuit board. On a real point-to-point Fender, it's a breeze. By no means was my comment a plug for my preamp. But of course, I'm always happy to offer that option.

I'm going to have to make it work with the TRRI. Funds are very limited.

It's all good Brad, I hear you about the issues with the RI's having a circuit board instead of P2P wiring being a pain in the ass. My repair guy let out a heavy sigh when I brought it in as it sits there with a pile of old Bassman, Twins, and others. I got such a good deal on it I couldn't pass it up. I miss my old Mesa Mark III and will put that back into use as soon as its fixed up. That being said, I do plan on selling the Twin RI, my old Marshall JCM 800, a VG-88, and a bunch of other stuff I don't use in the next 6 months and getting your preamp and a power amp. One thing I love in my gear is flexibility. Having the power and pre split up gives a lot of cool options.

I'll be fair. The RI Fenders are good. They aren't crap by any means. It's merely the difficulty in getting at the component solder points. My recommendation for anyone with a RI is that when they do get in there, go ahead and take care of as much as you can, take full advantage of the opportunity to upgrade the resistors and cap's, etc.

yep - burning a circuit board can be a costly mistake

I have almost fully upgraded my TRRI to Jerry specs. The process has a trick to it, you CAN"T BURN THE BOARD!!!! if you do, bye bye amp, and good luck fixing it. Go to the leg of the cap or resistor you plan on removing and HEAT THE LEG as close to the cap or resistor as possible. Don't worry about burning the old cap or resistor, its only worth 69 cents and they're not what you want anyway. keep a steady pressure under the cap or res with a plastic or rubber handle screwdriver. put this pressure on the end you're heating up. as it rises pop it out slowly and evenly. you can move it up a little at a time, just watch how hot you're getting it. You don't want to take the copper circle around the hole with it or you have another problem too(that happens if you melt the plastic too much).

I agree P2P amps are easier to solder, but RI's are easier to find the right parts!!! They are laid out neatly and numbered. Following a schematic is easy as pie. But, for all the ease of finding the parts, it is much easier to mess up the entire amp by burning or damaging the lead hole. There is a soldering Iron out there that is cool to the touch, I saw it on a late night infomercial. I wonder if that would be a good invention for this type of soldering. PLUS, through my tweaking adventure, Waldo and I have found that the schematic is not EXACTLY like the original, but very close and without an audible difference. They swap a resistor and a cap in placement here and there.

Hey there,
Just want to offer an idea: I had a TRRI (sold it & bought a Heritage Patriot). Mine did the same thing during a gig but I completely lost volume in the end. The plug on the cable going from the amp to the speaker box is bag. Regardless of the issue, these should be replaced. Cheap, quick and will save a lot of hassle down the road.

Peace,

Gil
