the hi-end cj stuff is the only one ya mention that offers remote, afaik, & even used, prolly outta my budget at present.
melos is supposed to be offering a revised photentiometer in the next couple of months, designed by mark porzilli, that won't be so suceptible to shipping damage - i tink i will swap out the alps pots in my unit when these are awailable... the alps pots, while nice, were a sonic step backwards from the original photentiometer, imho - one that melos had to do because ~25% of 'em were getting outta alignment due to shipping...
