So, bought a Grand "Fender reverb re-issue" reverb unit from Ali (supposedly free shipping)
Seller asked for more $$ for shipping, and I did so.
Arrived "not working". (got a $225 refund off a ~$600 investment)
The 6V6 plate/cathode had no connections, after adding/wiring the connections, ..it was intermittent (there was a fine strand of wire between some tube pins, may have been me, or?)
Anyway, decided to hack the "already beater" unit, added another tank (a MOD long, 3 spring-long decay) Original was a medium, 2 spring-medium decay.
Added a 3PDT switch, (for switching between tanks), took out the dangling participle power cord & foot switch wires, added a PEM & jack, a "real" 1W tone pot, chassis nuts, etc..
Still a "beater" but it sounds great!
