My CD player has an output cap but I often switch between another source as well (Mede8er HD player) and that does not have an output cap, so I'll have to add the input cap for the BoZ. Also, this will be used with the Aussie Amps Nxv200 (as you have built them as a poweramp). The Aussie amps does not have an input cap, so my BoZ must have the input and output caps.


Here is the link/forum/thread to a BoZ banquet. The PS is (from clean 35V DC source) 1ohm (5W wire wound), 15,000uf, 10ohm 1W, 15,000uf. So -> RCRC. I use 10,000uf caps 'cause I had a lorry full of them. I wouldn't go under 10,000uf in fact I would use high-end 15,000uf (about 40V) caps.

If the PS is not clear let me know I'll CAD it. I found the Russian 40y-9 PIOs excellent as input caps and Jaycar 10uf poly caps excellent as output caps - snub the 10uf poly with a 0.1uf

Sorry OT.

1uf input cap and 10uf ouput cap will give a bandwidth from 5 to 180khz. Jaycar have good poly 1uf caps.
