from last year modding the caps and now the resistors of my super cheap chinese 6p1 amp
initially i used an adapter to use 6aq5s in place of the 6p1. brimar, great change.
also mullard ef95s, would the sound be too cuddly? not if you clean the tube pins well, what a revelation. mullards and brimars sounding transparent pristine, who would ve thought it?
i also found that NOS paper oil caps (US and USSR) as good as or better than modern commercial types like rike and mundorf.
at far lower prices. far lower.
