amps and solutions

[Andy Le Blanc]

busy monday ........ all fenders.......

bandmaster blackface...... nice, almost all original it had some work a long
time back to the trem.... blown opt..... filter caps blown..... it looks like it was
stored in a very damp place ..... and it will still need a 50k pot and opto for
the trem...... nice amp.... sounds really good with the power side restored
original signal chain.... gonna have to clean the inputs.... again

red knob twin....... this one has been in a couple three shops since may
with a weird distortion....... no one could figure it out....great....wheres the
holy water..... turns out to be a fried 1 ohm resistor on a test point.....
these have the power tube cathodes connected to ground thru a really small
1ohm res. paired with a diode......so when the res. fries youll hear the
nonlinear distortion thru the diode..... sounds like an issue with the pre
but heres the rub.... the instructions to bias the thing are on the back
and theyer for ma. (.04 v)...... when this happens youll get readings in
volts from 25 to 35 v........ de da deee...

hot rod deluxe...... crackle pop..... screen grids and plate resistors....
thats the issue with these ..... if anybody tries to sell you any fender with
a noise issue like this talk the price down and turn it around for a profit
fender had vender bender.....
