Tried a vtl5c1 in ldr5 position but could get it to work correctly.
Trying to have hybrid power between relays and ldrs I couldn't work out, the component was a cheap Chinese copy.
Not sure if it worked from new.
Ended up using another relay which worked great.
There is a definite more defined sound without the 2 channels without bleeding into each other.
The other take is to use blue high voltage ceramic disk caps on the 1nf positions this cleans the sound up.
The sprague orange drop capacitors seemed ok in the coupling but if I did it again I would just use mallory 150 capacitors through out.
