Re: Peavey rockmaster preamp. Clean channel sounds distorted on main outs, but not on clean send

I don't know what parts are near the socket, some parts of the V4 CIRCUIT can be on other circuit boards even. You should definitely use 12AX7 in all sockets, at least until the problems are sorted out. You can experiment with any of the 12A?7 family, but V4 wouldn't be my choice for that. It is not...

Re: Peavey rockmaster preamp. Clean channel sounds distorted on main outs, but not on clean send

Well first, your signal has to go through a zillion jacks on that model, no matter what channel ypou use. SO first thing I'd do would be to clean the cutout contacts on every jack. You tested things like common send, but I see no report on testing the common return for example. Play through the comm...

Re: How to open up my Peavey 210 TX bass cabinet

Looking at photos I can see the speakers mount from the front. You can get inside by removing the grille, then speakers can be removed. As 1985 mentions, the rear jack panel comes off with a few screws, and generally if I do that I can reach the speaker connections from there. I have on occasion rem...

Re: Peavey Transtube 212 EFX

Many years ago - like 1970 - We had a simple sound system. Basic mixer with no reverb. The guitarist had an Echoplex though. And we played the Nilsson tune Jump Into the Fire. I ran to the stage, grabbed the Echoplex, ran back and patched it into his vocal mic channel. The Echo needed to match the b...

Re: CS 4080HZ Transformer

Transformers are highly specific, so contact Peavey Parts department and ask if that part is available. It is not an off-the-shelf commercial transformer,

Re: CS 4080HZ Transformer

WHy not just check out the amp and find out if the transformer is the problem? They can fail, but transformers are THE number one MOST reliable parts in an amplifier.

Re: Peavey Transtube 212 EFX

Well the loop is after most of the preamp. So if you have a delay and a fuzz pedals, if you put the delay out front and the fuzz in th loop, then your echoes are distorted. If you put the delay in the loop, and the fuzz out front, then your distortions get a nice echo. Generally, overdrive and disto...

Re: Peavey Transtube 212 EFX

You have two effects loops in the amp, one marked effects loop send and return. The other marked preamp out and power amp in. Use them just as you would on ANY other amp to get your effects units into the game.

Re: Help!! Peavey 6505+ 112 combo cuts off

Of course could be many things, but way most likely is a failing power tube. Whenever it has an internal fit, it blows your fuse. You replace the fuse, but the intermittent tube remains.

Re: Peavey Bravo output transformer

It won't hurt the amp to connect a 16 ohm speaker to the 8 ohm tap. Try it. I don't know what the primary impedance is, but I do know the output stage is one pair of EL84. Why not look for other output transformers intended for amps with a single pair of EL84s? Like a Peavey Classic 20. Or some such.

Re: Peavey Delta Blues Footswitch Question

You have the amp? Unplug any footswitch, is the trem still working? As far as I know you do not need a FS to turn on the trem. SO trem is always on. Turn the depth to zero if you don't want trem.

Stomp switches are push on then push off.

Re: Parts for Peavey VTM Bias Mod

Either one. You need a 1uf cap there of sufficient voltage rating for that cathode follower stage. That does look like a film cap, so it likely need not be changed. They don't really get leaky like a 'lytic. On the drawing I'd have to say it looks to me like they put the + on the wrong end. Of cours...

Re: Studio Pro 50 volume loss

Oh dear. NEVER connect the speaker out of an amp to an input. Inputs are designed to take the half a volt or less of the guitar, or even one volt from a line level source, but the speaker output of an amp can be 25-30 volts or in that area, and can damage the input amp.
