Hi

I could get a 1960s D130F 8 Ohm speaker, can I put it in a Twin Reverb Reissue?? Are the Twins 4 or 8 Ohms???

Yes. I'm not sure how much. I believe the
JBL D-130F is a great sounding speaker.

I have a 135 watt Twin Reverb that I bought a new MOJOTONE Vibrosonic cabnet for. It's loaded with a JBL D-130 4 ohm and sounds GREAT! Lighter than 2 12's too!!! (Not as heavy???)

Try the D130F in an extension cabinet, and connect the 12's in the twin in series. This gives an overall load of 8ohms + 8ohms (16ohms)in parallel with 8ohms (5.33ohms overall impedance),which is perfectly suitable as a load on a 4 ohm amp. Make sure all speakers are in phase. You can connect a 1.5v "D" cell to the speaker lead(s) ~momentarily~, to observe the direction of cone travel, to check this.

You could change the output transformer to one designed for 4 x 6L6 and an 8 ohm output (like a Vibrosonic Reverb). Also, Twins sound great for steel with 6550's but you have to add a pretty big filament transformer if you use 6550's to keep the amp happy.
