From the post
Happened to spot one on ebay for mere 250 usd. A bargain. For this layout, i omitted the buffers and electronic switching. 30K pot value may be hard to source, so one could try 50k pots for all of them. Original unit has 2SC2240BL transistors which are low noise devices with BCE pinout and hFE range of 200-700. I think 2N5088, 2N5089, BC549 or BC550 with gains at 400-500 should do just fine. The transistor image is for 2N* devices, so mind the pinout and experiment.

- 100pF red film cap between the first 220Ω and Q2 (centre of board): the unit letter is partly hidden behind the transistor, read as 100pF, could be 100nF
