More info coming soon!
However, right now I can say that I am finished dialing in the prototype and it sounds fantastic. Being that the 5F6a and JTM45 circuits differ only by way of a few component values, I have opted to tune the Speed Shop Bassman towards the Marshall so as to shift the performance toward a more modern blues-rock range.
I am currently using some great vintage output transformers that are extremely rare, so I will eventually need to source others when these run out - but a few early units will feature them.
All NOS caps and resistors are used, as well as the best new components available. A spare-no-expense Speed Shop machine - as usual.
Configurations include 2x10, 4x10, or head. Speakers are Speed Shop A10Qs, which sound terrific with this circuit, or others can be substituted by request.
Power tubes employed can be EL34, 5881, etc. Dimed output is pushing 50 watts RMS with EL34s.
Accepting pre-orders now. Please contact Rondo for more info.
