I can't say what would happen to dropping voltage, but you can crank the current up higher if the heatsinks will take it.
Understand the current/voltage dissipation relationship. As there is a domestic concern with living room audiophile real estate and remaining married, i wouldn't want bigger hearsinks/chassis (part of the reason for eventual monoblocks hidden behind speakers).
The main unknown for me is whether there is a voltage threshold below which the circuit won’t operate properly and whether some circuit values would need to change with halved voltage. I’m sure distortion will go up but it may be worth the trade off to better drive the ESL57s.

Starting work on the chassis. Went here to look for parts:
To enable a 12" wide heat sink pair:
(will need to remove that slight bump at the join to enable the aluminum bars to attach the two sinks).

Opened a couple of crates, and blew the 40 year old dust off these:
They will be used to join the heat sinks at the top and bottom.

Found these in a crate labelled "abandoned electrostatic panel project":
Thinking about using these for top and bottom ventilation panels.

My plan is to make a stereo amplifier using existing inventory. Once that is done, the boards will be migrated to much prettier (hopefully) monoblocks.
