Default Bozak?

Hi Tomy,

very good job!

I also have Bozak speaker and I would like to have some information about your
speaker if it's possible. How is the sound? where did you find the plan?

Tigrine

Thank You!
I used six polypropylene caps Acrotronics 425uF 700V in PS of output stage because need more capacity, but the rest of the capacitors is PIO with tin foil. Total capacity is about 3000uF. Energy capacity 70 Joule per 1 Watt. Output tube is an ex-USSR UB-180 triod, more then 70 years old (1939) with barium cathode. AFAIK it is the best for sound.

Thank You! I think B199 is very good woofer to my ears, but twitter doesn't. I replaced it with another Jensen RP-302A.
All the plans and schematic diagram are born in my head, I am already 30 years sound. All transformers and chokes is made myself. For example the output transformer for UB-180 weighs 12 kg and 36 square cm, Ra=12000 Ohm.

Filosoff, This is an English speaking forum. If you post in Russian you must also post an English translation.
