Received my 2275-130 today, SN B001497,
and could use some technical assistance.
Anyone have a schem. and layout pictorial?
Only schem. I have is in Tube Amp Book Vol.4, by Pittman, with the SS driver.
This amp has the tube driver, Reverb and Vibrato.
Pulled the chassis to check the caps in the can. All caps are Mallory, date code 74.
Caps are 2-100mfd@450, I located them on the schem, and
2-20mfd@450, did not locate on schem.[?]
4-150@50, located on schem. for 16V.
Located on small board by pwr. tranny.
2-150@50, on main board near pwr. tranny,
did not locate on schem.[?]
1-150@50 on a board under the out. tranny,
What is the function of this board? Vib?
2-pots on main board.
Which is the bias and which is the Vibrato?
One is close to the pwr tranny and near the edge of the main board.
What range can the bias be set?
Where is it measured, across the 3.9 ohm res?
I plan on ordering a set of JJ EL3Ls,
and driver from Eurotube in Oregon.
Some rust on the trannies. I'll use Rustoleum to prevent any more.
Fender knobs, clean control panel, and the Tube chart is faded. No date is marked on chassis.
Any help 'preciated.
Thanks,
