    I tried searching, too many hits.

    I found a mint A21 for a good price, all original but working fine according to the owner. I think this is the original, not the series 2

    How good is this amp for pure musical enjoyment? What concerns should I have? I assume (?) an immediate bias check and electrolytic cap replacement would be in order?

    They are wonderful things. Really good sounding amps, though need partnering with fairly efficient speakers as they are only about 10-12 Watts IIRC. Anything of that age will need a good service by now, a class A amp even more so due to the hot running.

    Very good sounding amp and always serviceable no matter what so can’t go wrong if the sound signature suits you well.

    Brilliant amps. Sugden will still service them if needed.

    Be aware though that Sugden has halted all non-warranty servicing for the time being owing to a backlog in the factory from covid issues.

    Not a lot to touch it IMO, at anywhere near the price. Such 'hifi' shortcomings as it has are essentially benign in terms of musical enjoyment, and easy to ignore.
