Heyboer Hy02272, 370-0-370: What can I use this thing for?

[martinman]

I have a Heyboer Hy022772 OT with the following specs:

PT:
HV is 370-0-370 @.060mA
6.3v @ 1.5 Amp and 5v @ 2.5 Amp

I had this in a scratch build 5f1 but the plate voltage was way high. I couldn't bring it down with a bias resistor, so I ended up swapping it out for something close to the spec.

So, what I use this for?

I'd use it in a tweed deluxe, but I'm not to picky about the HT voltages.
