I saw Propagandhi play two nights ago and mother fuckin' Todd (their bass player) uses the same amp as I do, but he's got a fridge and I've got a dinky 2x12. Now I want an Ampeg fridge again.

A local guitar shop has a Mesa/Boogie 400 (not the 400+, mind) up for $800. Haven't seen it in person, but the picture on the site (here it is) indicate that it was rack-mounted for most of its life and I have every intention of taking a closer look, maybe even dragging my Mesa/Boogie Diesel 410 into the shop and seeing what it can do. Most of the 400s I've seen available for sale are 400+s and are about a hundred bucks more and the only difference I've been able to determine is that the non-+ models use a dozen 6L6s instead of six 6550s. Any other issues? I'm actually kind of excited because I am in love with Sovtek (for no damned good reason) and would get to put 6 of their 6550WEs in there and watch my bandmates cry. I guess I'll be keeping my 800RB on hand, but is $800 a good deal for this thing? I wanna make the jump to tubes (hurrah for raises) and SVTs, while freakin' awesome, this 400 might be more up my alley, not to mention cheaper. edit: Off of the topic above, my guitarist bought new tubes for his Ampeg reverberocket head and one of the new matched tubes got much, much hotter than its pair; I was able to smell it from across the room and turn the amp off. Is this more-than-likely a faulty tube or something wrong with his amp? He's never replaced the tubes in this amp and when we put the old ones in, nothing went wrong. I know which tube it was, but I don't know where it is in the circuit off the top of my head. scuz fucked around with this message at 06:58 on Sep 4, 2012 |

This discussion has reminded me that I don't know half as much as I'd like to about tubes and how they work. It has also prodded me to find the RCA RC-30 receiving tube handbook, which I gather is a pretty dry but interesting-to-the-right-nerd read. I found it here: clicky and goddamn, this is fun!

So there's a band that I've been friends with for a while, and we've played with them a lot, and they've sort of taken off because their music is awesome and they play shows all the time (like one per week in the area). They're talented dudes, but their gear is what a 15 year-old grunge cover band would use. A 50-watt Peavey TKO bass amp (which I suspect is a keyboard amp), a Marshall modelling solid-state half stack that grates my ears off, and a Peavey ValveKing (which I guess isn't too bad). The lead guitar guy who just bought an MIA Tele finally asked me what he should get for a new amp to replace his Marshall half-stack, so we went and tried this: Fender DeVille 410 (came with a cover and footswitch!) and holy cow, this thing is awesome. We monkied around with it for a while in the shop before he decided on it 100% and I couldn't be happier. They play twangy punk rock stuff and this is a huge step up for them. And we were able to dial in a whole lot of awesome tones on this DeVille, but the only thing that I'm not sold on (the guy playing it is fine [so why even care, right?]) is palm-muting. It sounds a little flubby and dirty during palm-muted chords and I think part of it is the Tele, and the other part is the amp itself. I could dial out most of it using the EQ stuff, but I'm wondering if anyone out there has any of their favorite settings on this bad boy. As for discussion-type stuff, what can we do for their Peavey? I'm thinking just another one of these, or (since he plays backup) maybe just a Fender Hot Rod 212? He's playing a Gretsch hollowbody through that head into a Marshall 1960B and it's just not cutting the mustard anymore.

There's a Mig100 on my local craigslist that comes with a Carvin 412 cabinet for $600. I wanna buy that thing and convert it into a 2x12 combo amp. Crazy idea or awesome idea? I've never done anything like this before, but I really like the amp itself and don't wanna plunk-down a grand to get a DIY kit.

Hokay so there's a Marshall JCM 900 4502 2x12 combo up for $500 at my local shop. It would be replacing a Peavey VK100 + JCM 900 4x12 and play alongside a DeVille 4x10. How would this hold up? The combo is a must-have, and we just can't get the VK to sound good. We've decided that the options are that 4502 combo, or get a JCM 900 and put it on a 2x12 cabinet, but we'd prefer the combo.

iostream.h posted:I beat the holy gently caress out of one of those for a couple of years, the only real issue I had was the tube sockets getting a little loose, no big thing. Portability. The lovely half stack is such a pain to haul around and we play out weekly. Everyone else has a great-sounding compact setup, so why not this too?

Friend of mine needs his JCM 800 2302 worked on a bit and he's letting me do it! He wants the tubes changed to EL34s and I haven't done anything like that before. I'm no dummy when it comes to electronics, and I'm very careful in these things, but is there any definitive resource out there for this kind of thing?

So I've started this 6L6-to-EL34 conversion and I feel very out of my depth. I think I've finally managed to pick out the resistor that I need to double, so the project is going to be finished, but I need an amp of my own for practice. Is there a certain type of tube amp that would be good for me to experiment on without breaking the bank? I'm thinking that if I post "I will buy your broken amp" on craigslist that I might wind up with something good, but I'm also curious as to where the techies in the thread got their start. Also where do you guys go for tube amp service tips, gurus, and general info, like forums and stuff? scuz fucked around with this message at 01:53 on Jan 8, 2014 |

Did some work on my buddy's JCM 900 4502 combo yesterday and noticed for the first time that he's running EL34s in there. Is that standard? I'm thinking they were sent out with 5881/6L6 tubes? I didn't see any modifications done on the inside but the bias was jacked all the way up. I kinda wanna try it with 6L6s instead, just wondering if that's what they came with in the first place.

Speaking of Peavey amps, this bad boy just showed up on my local Craigslist: http://minneapolis.craigslist.org/csw/msg/4295220717.html I do not play guitar, but I have been trying to do tube amp repair for my friends. Would this be a decent critter on which to learn the magic of electron manipulation? I figure at only $200 it would be a good place to begin.

Agreed posted:At least they do have a good clean channel. A quick once-over by a competent amp tech can bring a lot out of a HRD, though - both in terms of making the dirt channel actually usable, but also in improving the general responsiveness of the clean channel, replacing the linear pot with a more appropriate taper pot, a little bit of adjustment to the tone stack to help with some flub in the mid-bass frequencies that is amplified (no pun intended) by the speaker choice and construction...  I just modded a JCM 2203 to accept EL34s instead of the 6L6s it came with to great satisfaction from my guitarist buddy so I feel like I can take on anything. Friend of mine has a HRD 410 and he uses the overdrive channel a lot. While it sounds way better than his SS Marshall half stack, I agree that the dirty channels could use some work.

Been looking for a cheap practice amp for my house and stumbled across this Yamaha B30-115 combo that doesn't work. I know my way around a schematic and am no stranger to fiddling with this kind of thing, but I am unfamiliar with symptoms afflicting amplifiers. Is this description enough to give anyone a clear "stay away" or "yes that's easy" diagnosis?quote:here we have a cool old Yamaha 115B Amp. Right now it powers on but does not make any sound. It sounds like the pots are quite dirty as the only sound it does make it some loud crackling/popping when you turn the volume knob. In working condition these are super solid amplifiers, so if you're handy with repair this might be a slammin' deal!

Well that's a little bit of a story. I bought it thinking it was broken (it wasn't but the speaker I bought with it was), attempted to replace the 30 year old capacitors, but I installed them backwards by mistake. The tech corrected my error and bench tested it for a few hours and everything was working fine.
