Up for sale, an assembled PCB for Phono preamplifier, ready to install in chassis. For RIAA moving magnet cartridges. Dated 2015. Includes 3 used Euro 12AX7 tubes, 2 Amperex Holland and a Telefunken. I used this in a line/phono preamp and decided to go a different direction. The circuit is supposedly based on the excellent EAR 834 design. All factory soldered, w/ quality MF resistors, Wima and Philips capacitors. You need ~285VDC for tubes and 12VDC for tube filaments. Inputs and outputs easy to connect, you can place an Alps blue Vol pot on the board, if you want.2 of the 3 tubes have their printing worn off, but they test well, 1200+ gm (out of 875 gm min.). Tested on Hickok 539C tester. Buyer will receive 1 complete board and 3 tubes, as shown. Asking 95.00 plus ship. Will be well-packed and shipped within US, $8 by US Postal. -Pete
