One of our Mangatone Panoramic Stereo Combo amps came over with no reverb, with a broken internal xfmr pin wire that I wasn't able to restore, so had to order another 4AB2C1B tank....put a 4AB3C1B tank in for the time being just to check it out. Only difference there is the decay...the 2C is a medium decay, 3C is the long decay.
The service note taped on the amp only mentioned the Reverb being out. No mention of the Vibrato function.
The amp didn't come with the foot switch, nor the Remote Pedal. It's been long enough for me to forget whether the Remote Pedal or Foot Switch have to be plugged in for the Vibrato / Tremolo to work. As it is, that's NOT working. I've plugged in shorting plugs, open TRS plugs into the front panel Remote Pedal jack with no difference. There is a long TRS cable that's plugged into what I presume is the Foot Switch jack, and shorting Ring to Sleeve will control the Reverb, but doesn't do anything for the Vibrato either.
The Owner' manual (data sheet, really) doesn't give any clue. I don't have any 12DW7 tubes...an ECC832 tube is installed, it being pin-for-pin compatible (has a 12AX7 and a 12AU7 section inside). Tried both a 12AU7 and a 12AX7 in there with no difference. I thought one didn't need the Remote Pedal or Foot Switch plugged in for the Vibrato function to work. I don't have service document on this amp.
