Greetings Grant gnnett & welcome.
Yes, I am using the CT & one end of a single winding. Is this what you mean? (Can't parallel halves of the CTapped winding of course.) DarkLantern blog - darklanternforowen.wordpress.com

I have a a toroid with 2 separate windings of 18V,2.2A, to try with a Lounge LCR sometime this year. Cheers Grant

An update:
The Toroid PTX that installed (above) hummed a bit & whilst the hum is only low level, I have found that 'noise-floor' does affect reproduced sound in-room (more later). So, I happen to have a few tossed-out chasses from high quality 12-channel multi-room amps, with Taiwan-made toroidal PTXs. These PTXs have 'universal' 100/120/220/240Vac primaries, a 20-0-20V secondary winding & would be 40-50x times the VA voltage-current capacity (300-400VA) of the original wallwart. The PTXs were nice & quiet on test, so the following was 'breadboarded' up for audition (using 1/2 the CTapped winding to get 20.6 to 20.9Vac out with the Lounge LCR connected):   Now we're beginning to 'cook', the sound seems more open, dynamics more agile, treble seems more extended & 'sparkling' (lower noise floor?) Have to admit, I'm a little surprised. DarkLantern blog - darklanternforowen.wordpress.com
