I have designed a small filter board for use in my Bass amp and to get the best prototype PCB board pricing i needed to have several made at a time if anyone would be interested in one at my cost.
Each board is about 3x5" and contains 4x 15,000uf 80v 35x60mm filter caps set up to provide independant dual + and - outputs with fuses inline with each of the 4 outputs. the HV side is dual layer with duplicate top and bottom traces with single sided plated through hole traces for the regulator section.
PLUS a layout for the Pass Zen 3 +/- voltage regulator to power a lower voltage front end. The regulator is set up to use TO-220 type pass devices. I have not yet tested this layout, but i havecomplete faith in Mr.Pass's regulator designs, i mean come on who wouldnt right??
You could just use the PCB for the filter caps and fuses and not use the Low Voltage regulators, or??
Each board will come loaded with the filtar caps, fuse holders, and most of the regulator parts including the TO-220 Pass mosfets.
If you want the regulator section loaded up to Provide +/- 15vdc the same as what i am using, i will do that at no extra charge. otherwise i will load up the regulator sections and leave the Zeners and associated resistors off for you to DIY.
I am still calculation the final costs. but each board will be around $50.00 at quick glance of the parts cost's.
Again i am not doing this for profit, just trying to help offset my cost of having one of these made for myself!
and if you have a SWR SM-900 bass amp, this should be a drop in upgrade board for your amp!!!
