Vox super beatle

[pontiacpete]

Can anyone tell me which beatle this is by the photo I posted? This one came to me with the power switch wafer broken off completely. I jumped the speaker line on the wafer and connected the wires on the mains switch. It powers up but there’s no sound. There’s voltages on the pre amp board and signal is coming in at the 68Ks. And the signal from what I can tell is leaving the board. I think this is still in stand by.
Can someone tell me if it is and how to get it in play mode? Also, can someone recommend a schematic? I’m thinking this is the 1141, Also what can I do about the power/standby/lights switch? Would a 3 way DPDT toggle switch work here? I remember putting a rotary switch for a del ray a while back, I think.
It says super reverb and has tremolo and MRB.
Thanks

Thanks for that!. I got it working, didn’t have it completely set up right, needed to plug in the RCA to the pre module. It wasn’t in standby since I jumped the speaker wires on the broken wafer (brown/white stripe), that’s the standby a break in the speaker.
Now i have to find where the other reverb RCA connected went, there’s only one.

Thanks again!!

I have this switch from the teisco power switch repair that you can see at this thread:

https://music-electronics-forum.com/...-repair/36242-

It’s C&K(9) a series 3 position rotary with 12 lugs around the body and 4 lugs in the center label A-D. It’s rated at 2.6A 125vac.
Would this switch work for the super beatle? Or do I need one rated for higher amperage. The amp uses a 3A fuse.

Take a look at the front side, and see if there's a Repeat Percusion switch there. If so, it's a V1143. That's the one I have here in my shop presently pulled apart, waiting for parts. That function isn't on the V1141 Beatle Super Reverb. The Preamp PCB in the unit I have here looks a little different as well. So, we both have one of these gems apart for surgery. Should be able to compare notes, up to a point. I've ordered 10,000uF/63V Snap-In replacement power supply buss caps and 1-3/8" dia mounting brackets. Though seeing how close together the cap cans are on the power amp chassis, I suspect THAT is going to be a real challenge installing those!

It has “MRB effects”. Is that the repeat percussion switch, if not what is it?
I’m trying to wire the power switch using that switch in the picture. Do you know which light comes on when it’s in standby? Does the red light come on first at power up then when in operate mode does it go off and the green one comes on?

edit: I see MRB means ‘mid resonant boost’

V-14 or V114 Super Beatle
http://www.voxshowroom.com/us/amp/beat_head.html

Two separate foot switches were provided with the amp. A two button foot switch with a 1/4" TRS (stereo) plug controlled the reverb and tremolo. A second single button "egg" shaped foot switch remotely controlled the MRB feature via an electro-magnetic relay located inside the amp. When the MRB button was depressed on the foot switch, you could actually hear the clicking sound of the relay from inside the amplifier.

The Super Beatle predates the Beatle.

When John Lennon saw the "Super" he said "nothing is better than the Beatles" and had them remove the Super.

Is the rear panel missing? That's where the model number plate (with serial #) is.

No need.
The back panel says it. #10
