Hi Mike,

I measured 340 ohm DCR for both primary and secondary. When I ordered, I specified parafeed version with channel frame. The unit was written "RIT-5 PF M6", so I thought it's Senior version.

I connected the transformer as follows:

Primary,
Tube's plate -> 1uF coupling cap -> Red lug ... Blue lug -> GND
I also switched the Red and Blue and got the same result.

Secondary
White -> power tube's grid ... Black -> GND
I did test with and without 27K resistor terminated. It didn't make different result.

I used sine wave 1KHz for testing. The output looked good to about 100-110Vpp. Then it began to look like sawtooth after 120Vpp.

Please let me know if there might be something else I could try. Thanks.

Karin
