Was assisting a friends' friend with minor maintenance on his Quad 33.
Sounds ok initially after power-up but takes about 25-35min before sounding right.
Hence only replaced the two main EC on the PSU and a few of the older poly(s) on the DISC board (see pix below). Used an older generation of poly(s) for the DISC board, to maintain the sonic charm as much as possible.
Sound surprising decent with clearity once more.
They don't make them like they used to these days - not put together with "love and tender loving care" these days, just mass production for the sake of profits.
