Classictone has larger transformers that I'm pretty sure fit the bolt pattern and cutouts of the originals. I would just buy a Showman Reverb head, though.

Depending on the stock speaker, this could make a tremendous difference. I can't tell you what the stock speaker's sensitivity is, but it's probably not hard to beat. Look for a speaker with a high sensitivity rating (>100dB). My Eminence Wizard 16s have an absurd sensitivity of 103.5 dB and my Wizard 16-loaded 2x12 is louder than most 4x12s I've used.

Agreed on this point. I use an open back 1x12 cab loaded with an Eminence EM12 (their EVM12L clone) and I am still very loud- like complaining sound guy loud. I bet if you swapped in a high efficiency speaker and made a little 1x12 with another good speaker, you'd be there. I played some very loud rock shows in the UK using borrowed AC15s or Peavey Bandits, unmiced, no problem.

Not without modding the DR to add a line out.


This got me thinking...

Anybody here tried something like placing an L-pad in parallel with the speaker load? I think my calculations are correct:

An L-pad with a total resistance (series + shunt) of 5k would have a nearly negligible impact on total load to the amp (7.98 ohms with a theoretical 8-ohm speaker).

Padding down ~30 dB would take 4.7k series and 160R shunt resistors, using standard 5% values (actual pad: -29.65 dB).

100w into the 7.98-ohm load is about 28.3V across the load. 28.3V across the pad is about 165 mW. Voltage across the shunt resistor is a little less than 1V, or about 1.6 dBu. That’s plenty low enough to run into a power amp, and halve all of it if the amp is only making 25w.

So am I missing something here? Adverse tonal implications?

I believe that's exactly what the line out on my Weber mass attenuator is doing and i've never had issues. Tonal implications... yes - is it bad? I don't think so, I quite liked the sound.
