Pair 3.5k PP Japan Output Transformers

[soulmerchant]

Hi All

I have a pair of nearly new Tomiko Japan 3.5K OPT's. These sound pretty nice for the price. I am looking for 220 Swiss Francs plus shipping for them.

Here are the specs:
Primary impedance 3.5K
With UL tap at 43%
Approx. 1.1Kg each
4 and 8 ohm secondary taps
Quoted Primary DC 225mA (max)
Quoted 35 Watt with 42 Watt max
DCR 185 Ohms, 29H

The seller I originally got them from quoted frequency range of 10Hz-88KHz (-3dB) but this is at 1 watt... nonetheless I found them pretty decent.

Also he quoted they are good with 300B, 2a3, 211, KT66, 6550, 6L6, KT88, EL34, etc...

I tested them with 2a3 and EL34. Sound was very good with 2a3 (sorry, no frequency sweeps or square wave evaluations). For EL34 in pentode, sound was also very good but I did not push them hard.

Pm me if you are interested.

These are still up for grabs in case someone is interested.
