BOSOZ preamplifier kit for sale

supernet · 5th July 2008, 09:47 PM

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)

As few people ask...it is possible to buy a BOSOZ kit without two transformers, the post costs are then reduced.

Email me for details....

Kevin and "meanman1964" you got my email.

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
