My first amp was an Alba UA 700. It was great. It’s now up in my loft awaiting repair. I only stopped using it and replaced it with an Arcam Alpha+ because the dual ganged Volume and Loudness ‘pots’ developed flat spots and loss f signal in certain positions. Shame !
Robroy.
They say you learn something every day - I don't - but I have today.
I had no idea that there was a UA-700 model.
My Uncle gave me a list of things to buy as my first system....which included a Philips! GA-437 turntable (still working 46 years on) and the UA-900 amp.
The day after I bought it, the price dropped.
I must have had the cheek to complain and, to their credit, good old Comet refunded the difference.
Get the 700 out of the loft Robroy - I've just seen a picture and the nice wood surround is all the rage now 😉
Hopefully those 'flatspots' are just contamination that will be cured by a few blasts of Servisol Super 10.
(Looks like you've got loads of switches and rotaries that will all benefit 👍).
