As seen on picture below,my BOSOZ kit contains:
two encapsulated 230 V / 2x38 V 30 VA toroid transformers
two main pcb boards with Mundorf 10uF Mcap output caps and two 1200 uF /63 V Panasonic FC power supply caps, bypassed with MKP cap
two power supply pcb boards with 1200 uF 63 VPanasonic FC caps and smaller FC caps for decoupling
The preamplifier is in perfect working condition and can accept both unbalanced and balanced I/O connections. My version was designed to operate at +- 45 V, if you want higher voltage, you need to replace power supply Zener diodes and use other transformer.
Price : 100 EUR + post cost (my location is EU)

The kit is still on sale...
This is exceptionally good sounding preamplifier and with audiophile grade polypropylene caps such as Mundorf MCAPs, it is very hard to detect any difference in transparency between this design and passive design...except additional gain...
New price...
60 EUR all kit
45 EUR without transformers

An externally hosted image should be here but it was not working when we last tested it.
