Triode conversion for VTL Renaissance 80 monos

Can anyone tell me what would be involved in converting my VTL Renaissance 80 monoblocks to triode operation? Opening one up, I can find and identify the power tube socket pins, and I think the wiring to them would need to be changed--but I don't know what the change(s) would be. If anyone could tell me where to find a schematic for these amps, that too would be very welcome, and I'd be most grateful.

That might void the warrantee.

These are decades out of warrantee. I called the company this AM and they were most unhelpful. For $150 and shipping both ways, they'd look at one monoblock and SEE if it could undergo conversion to triode mode. You'd think someone there might know, but I guess not. I've given up on the idea. Happily, the amps sound gorgeous in their present mode, which must be tetrode. I've decided to be happy with leaving well enough alone.

hi tom:

i own a pair of vtl deluxe 120s. they use 807 output tubes. they operate in terode and triode mode. i am surprised at the attitude you experienced. i bet a qualified technician could determine the feasibility of conversion.

if it were possible, you would probably lose more than 40 watts of power.
