I designed this last year and is now in production, I have 12 units available. Plate voltage has been stepped up from 190VDC to 240VDC and the 8-10VDC
heaters are now 12.6VDC. Its about 28.6-30VA making it more than twice
the power of the original and the MDRT and Mercury Magnetics
This lowers noise, expands the headroom and clarity and adds some edge
to the gain characteristics and has a tighter bass response. I designed
this because I use several Three Tube Mod boards and the original
transformer was not designed to handle (3) 12AX7s. I have 12 available.
