OT primary screen taps

Post by duriehill »

Hi guys

I have this output transformer for my upcoming Rocket build.

I noticed it had 'screen taps' on the primary side at 40% of the primary voltage..

See:

Any suggestions on anything cool I could do with this?

Merry Christmas

You can use them to supply the anodes in the LTPPI. This will add a little feedback in lieu of using feedback from the OT secondary. Pay attention to the phasing.
