Title: scott 223 monoblocks?
Post by: ecofan14 on October 27, 2015, 06:09:52 am

Hi there guys, just trying to build 2 of these monoblocks on 1 chassis, has anybody got a couple of decent pics of the actual parts inside. Of 1 of these or know where I can find some,? It was  designed in 1957, I can't find many pics if any of the insides of one, & I don't really want to subscribe to radio museum, finding some of the values of the capacitors a bit hard to understand, like 20,000mmf, which I think is 20nf, & does anybody know which is the low pass filter, & which is the high pass filter,? Cheers for any help in advance,

I would just buy the Sam's folder from eBay...

Photofact Folder, Howard W. SAMS set 349 folder 11

I don't see anything on the schematic that I would call a low pass or high pass filter.

20,000mmf = 20,000pF = .02µF = 20nF
