Hi Folks,
Got a new offering and as per usual, going to offer an introductory exclusive for the DIY Tube crowd
The RCA phono preamplifier in the RCA Receiving Tube Manual got a 21st century upgrade, including a line driver.
Attached is the board I made (awaiting tubes for a listen Parts and sockets not included ), a parts list and schema. No docs yet.
To use the board with a a PAS2/3, use a 10K dropper for the phono PSU instead of the stock 39K and use heater-balancing techniques (will post later)
Regular: $27.50 USD
DIY Tube Introductory: $25 USD!
Cheers!
