12AU7 Preamplifier Blair Chapman

This preamplifier is a 12AU7 tube based preamp in SRPP configuration. Features a layered plywood chassis, 2mm thick 6061 aluminum top plate.

- Gold plated RCA connectors

- Low noise toroidal power transformer

- Power supply is all point to point, but mounted to a piece of 1/8" fiberglass

- Audio circuit is full point to point

- High quality new tube sockets

- Alps (Real and NOT eBay replica crap)

- RCA tubes

If you look at the images, this unit is dead flat from 20Hz-20kHz! Look at the sine waves at 20Hz (Sorry, it is hard to snap a picture at 20Hz), 1kHz and 20kHz.

I have been doing this for many years and maintain my reputation as one of the most honest and reasonably sellers. Please let me know if you have any questions.

I rate my gear 8/10 due to the DIY nature of my gear. All components, minus tubes because I prefer older tubes are brand new and high quality. The smudge looks on the top plate are simply finger prints. It is a swirl sanded look that I will clean with alcohol before shipping.

Thank you for looking!
