Thanks! It's my #1 stage amp. The lil' G-18 is my preferred jam amp, because it sounds great without destroying anyone's hearing.

That, my friend, is my 1976 VT-22, aka 'The Voice Of Gawd'. A V-4 is the same thing in a separate head instead of a 2x12" combo. And yes, that's a quad of JJ KT88's. :D Just plug 'em in, and set the bias!

Then stand way back!

[QUOTE=PRSplaya]What do you think would be a reasonable price for that head? Don't want to pay too much for it. Looks to me like it's already got a grounded plug on it. Anything else I should watch out for since I probably won't get to try it out before buying it.

Anything you can't actually try out is a bit of a crap-shoot. Prices seem to range from $200 - $400, depending on condition. For $400, it should be in nearly pristine condition, no issues, ready-to-rock.

You should take it to someone who knows about such things to be sure that the 3-prong AC plug was installed correctly. And be very sure that the polarity switch is completely disconnected, along with the AC grounding cap.

Any 30 year old amp is probably due for fresh power supply caps. Take that into account as part of your bidding decisions. If it's been sitting in a closet for a long time, the caps are going to be in rough shape, and at the very least will need to be re-formed. If played often, but not cranked, it should be good to go.

[QUOTE=stahlhart]Without any socket wiring changes or re-biasing? That would sure make it easy... cool.

Follow that 6L6 link in my previous post. My VT-40 (VT-15?) is still running the original Ampeg-labeled 7027A tubes. My VT-22 had two different pairs (?) of 5881's in it. I installed a fresh quad of KT88's. Any time you change the power tubes, you should adjust the bias. Fortunately, it's relatively simple to install a multi-turn trimpot in the bias supply to make the bias adjustable. Much easier than swapping out resistors to try to get the right bias voltage.
