Moving some audio for some audio. Preamp is in appearance 9/10, functionally I'm giving it a 9/10, as Brian @ Raptor electronics just worked it over and maxed it out as far as he/we could go. It sounds awesome.
Replaced select resistors with Caddock and signal caps with the SS caps . Instead of passive left right isolation installed active similar to the 3aSS. Upgrading it to the level of a Red Rose Model 3a with enhancements.
Upgrading supply and filter caps with long life types. Additional filtering is installed to improve channel separation and an added transformer for the filament installed. Grid and cathode isolation is added.
All original packing and will add another box on top of that.
Buyer pays PayPal fees & shipping.
