New guy with a MM 112 RP100

Just picked up a RP 112 today local for 400.00 cash, fairly clean, sounds great, reverb was changed to a small Ruby tank and the speaker is a God awful heavy JBL e120 . Im trying to figure out how to make the reverb more surfy instead of a hall sound and looking for a lighter weight speaker for this beast, Thanks for all that respond, this is an excellant forum.I also see the tubes are EL34 and not 6v6 or 6l6?

My '81 RD 100 had a small tank!

I changed it to a 4 series "Mod" tank, and got a fuller reverb.

Thanks for the tip! I

Thanks for the tip! I actually just bought a set of J&J EL34L s and the reverb has gotten quite a bit stronger its more like a hall verb than a spring type

Short is standard

The RD and RP series all came with short type 8 3-spring tanks. I have only seen Accutronics and O.C. as OEM units, but the new MOD units will work fine. If one would like the longer decay of the 17" tanks, I see no reason why it wouldn't work in the 2165 chassis amps (RD/RP 65 and 100). They will not work in 1650 chassis amps.
