hi everyone!
here is the real story:
ARC gear that was produced in the 80s was the best ever made, period.
Problem: in those days premium hi fi parts with todays technologies where not available. Caps, resistors, volume pots, internal wiring, connectors, solder, plugs.
Huge progress in these areas made in the last 30 years.
If you have time ,money and basic skills, replacing above parts within ARC gear of the time, will yeald incredible results.
As for tube supply, this is a big issue. Unless you own a tube tester, you are screwd.
NOS tubes are a gamble. Today's tubes are best bet, provided you buy a large amount of the same production batch.
Here are some parts manufacturers: V caps, vandenhul wires, WBT connectors, TKD stepped attenuators (type C minimum), Caddocks tfts, vichay nude, Mills, fred diods.
Ps electolytic caps in ARC preamps must be replaced with polyprop
The sp10 has space on top and bottom of board to do so provided you lift the whole chassis. The 8s need an external box.
Hundreds of working hours, but then you have a killer, and W.Johnson will bless you from his other life.
