Title: Gretsch Twin Reverb - Looking for a schematic
Post by: LooseChange on July 25, 2011, 07:29:49 am

Serious search has come up with nothing.
There are two Gretsch twin reverbs... This one has two 6L6's and is a vertical 2x10. It's not the 6162.
Pic below is from thee web. Mine is a bit more beaten.

Thanks!

Any idea at all about model #? I'm sure you already found these:

Gretsch 6144
Gretsch 6150
Gretsch 6151
Gretsch 6152
Gretsch 6157

There's also a 6163 listed, pre- and power amp sections.

I don't suppose someone changed sockets to run the cheaper tubes? I saw the 6162 apparently uses expensive, hard to find power tubes. Sorry I came up empty!

LC, I looked at that 6163, and the power section does show 6L6s. But the preamp shows a total of 6 input jacks.

What I'm trying to say is, I'm no fricken help.  :laugh:

Thanks John. The circuit is true point to point and is a bit difficult to navigate so far.
Anyone else think they may be able to find this schematic?

Didn't find a schematic, but looking at this catalog page it looks like you have a later model 6162:

Besides the power tubes the old 6162 schematic is probably not too far off.   :dontknow:
