reverb in cal .50+ with 6L6 fault or feature?

[black_mesa]

Hi guys,
first post, so don´t kill me

I owned a V-twin pedal and a Subway blues (back in the days).
Recently I came across a caliber .50+, from 1990 which I bought for cheap,
opened it up, cleaned everything, changed the tubes, plugged it into my TL806 cab and !wow!. Pure awesomeness!

Just 1 question left: the reverb is dead silent, no signal or whatsoever, tried every position of the knob, scratched the springs insige the chassis, but it´s completely silent (better: dead).

I´ve got no footswitches at the moment and the seller told me, that it worked, while using the footswitch.
But there´s just a socket for EQ and one for lead /rhythm?
It´s not possible to hear the reverb without any footswitch?
Connect the send/return jacks??

Is it a feature or is there something wrong? I got no clues atm.
The 6l6 are brand new, V4 is a 12AT7, the 0.01 coupling cap ist fine....

Any help / advice will be appreciated,
thx
regards,
Carsten

Was the reverb working before you cleaned up the amp's tube sockets?

I couldn´t check it, because the two 6L6 were missing at that point (I had to order them...).
took out the 12AT7 / 12AX7 and cleaned all jacks with DeOxit

the channel and eq foot-switching is working.

I chop-sticked the connections and there seems to be no loose connection, it´s all in place.

will start to check everything now with the dmm...

the only resistor which seems to be faulty, is the 22k 2watts R261
I measured around 33k instead of the 22k. The colour coding is correct, so this one seems to be faulty.

Is it possible, that +10k are responsible for a complete fail?
At least I would expect to hear some kind of reverb, instead of nothing...?
