Bryan James	Re: question about marshall filter caps the 1959 and the 1986 has the 50/50 in the preamp section. i think i've read somewhere that you should filter caps between every set of 2 tubes when you step down the B+. but if you look at the 1959 or 1986 they are putting filter caps every time they step down the B+. i would think they are doing this mainly to block noise for the previous stages besides provideing a clean B+ or atleast that's my main thinking why they would be there i could be wrong.
