i think that if you want to be authentic, you'd need the 1204-43 for the power transformer, and the 1202_84 for the output transformer. + a C1999 4 hy ( Drake 354-114 clone ).

I ordered my 1202-84, 1204-43, and a 3H choke from Marstran. The build sounds awesome, and is my number one amp since March when I fired it up. I'll have to reform the caps on my other amps since they get no playing time anymore.
You can also order Metropoulos spec transformers from Heyboer (details at the MetroAmp store). I'm sure you can't go wrong there either.

Since I was on a budget, I got some used Heyboer prottypes from someone local for the OT and PT. Bought a Classic Tone 3H choke. Very happy with the results....
