Hello, does anyone have experience with this transformer,
is it suitable for interstage in SE tube amplifier, 6SN7 to 300B ?

Specifications:
Maximum Input: 2.5 watts (RMS)
Input: 10,000 ohms
Output: 15,000 ohms
Frequency Response: 20~20,000 Hz, +/- 1 dB
Insertion Loss: 0.5 dB

I've used the XSM10K/10K as an interstage quite a few times, but not the 10K/15K. If you pull less then 2ma DC through the primary of the 10K/10K you can get away with series use, otherwise you need to parallel feed the interstage. If you use the 6SN7 I expect you will have to parallel feed it. You can use a CCS, resistor or a plate choke on the 6SN7 plate. Sounds much better then the cost suggests.
