I have a pair of 10K:8 ohm parafeed transformers rated 1W, and a pair of 70H, 20 ma chokes. I tried using the 10, 10y, vt-25 but it was always too noisy. So I am looking for circuit ideas involving fairly high plate resistance tubes that can be run on 20 ma or less. Thanks

At one point I had such a pair of Magnequest transformers (maybe you bought them from me on eBay?) and I also couldn't figure out what to do with them...

They are potentially useful in the SEX amp with headphones or incredibly efficient speakers.

I did indeed get them on eBay but these are Electraprint. I am thinking they could be used to drive a horn in a multi-amp situation but I still need a circuit ;D
