Title: 1960's Gibson Amp reverb connections?
Post by: Packerswin14 on December 21, 2010, 08:24:52 pm

I've worked on quite a few amps, but haven't ever had trouble connecting a simple reverb tank.  I've got three old Gibson/Epiphone amps, finished restoring one of them this week.  The other two both use a standard reverb tank, but only have one RCA connector on the Chassis.  How does the reverb tank connect?  There's only one RCA jack, I've searched all over, why can't I figure this out?  The two amps are an Epiphone Regent EA-16 RVT and a Gibson GA-19RVT, both '60's vintage.  Any clues would be appreciated.  Merry Christmas!

Do these amps have a reverb driver transformer?  I've seen Gibson take the secondaries right off the transformer with an RCA jack directly to the pan.
Tell us what amp and we may be able to provide better info.

Thanks!  You nailed it.  I looked at the reverb tranny, and only one pair of wires going into the chassis, with a couple of connectors on top.  Grabbed a spare RCA cable, and that was it.  THANKS!
