Returned home with these Quad II monos today. The seller had owned them new since 1963! Also got the 22 pre and FM1 mono tuner. Original valves too:
I’ll be asking Rob at Amplabs to give them a full overhaul, new sockets (IEC & RCA) and perhaps a respray as there’s some rust type marks on them. Really enjoying some Sinatra vinyl of similar vintage via this classic system this evening.
I have identical units, also dating from 1963 or perhaps 64. They were my Dads but in need of a total overhaul unfortunately, similar rust issues too. Interested to hear how you get on with them.
