Reverb not working

[4406cuda]

I just picked up a Mark III Blue Stripe Simulclass Head with Reverb and EQ from the original owner. It came with two foot switches. One for Lead/Rhythm and another for Lead/Rhythm. I can not get the reverb to work, i checked the connectors and reseated all tubes. Do I need the Reverb/EQ foot switch to make it work?

Do I need the Reverb/EQ foot switch to make it work?

No. Check to see if you have a good ground at the reverb tank. Use an ohm meter to check for continuity to chassis ground at the reverb tank end of the grey RCA cable (outer ring), and of the tank itself when the grey wire is plugged in. 8)

If the reverb was switched off when the footwswitch was unplugged it can be in the off state, you will need to connect the footswitch and turn it back on. I recently had a similar issue. Another thing to check is make sure the reverb connections are not reversed.

Quoted from the users manual, the footswitch does NOT turn the reverb on or off.

" REVERB
Like the Presence, this control is located on the rear panel of short chassis amplifiers ... because there's no more room on the front and
they seldom require adjustment. The Mark III's reverb is by far the best we've ever had; its performance is hard to equal even with
expensive outboard effects. And the Reverb Footswitch also works uniquely: rather than merely switching the Reverb on and off, it
allows you to maintain a good background level then footswitch up to a dramatic, fully drenched reverb for a special effect. "

Which cable goes to the input of the reverb tank, grey or white?
