SS: I had some good ones: Loved: None,
I recommend you go for a tube amp 35-45 wpc,
with remote volume, and remote balance would be a great feature. Mono/Stereo modes.

SS, IF I consider SS, it is Receivers I have ’liked very much’, Sounded great, I just prefer vintage, tubes, and tube sound
my Tandberg 2080, 2 phono; 2 tape, features up the kazoo, great Radio, and 3 sets of speakers

Tandberg Died (my fault), I replaced it with a terrrific Yamaha CR-1020. If thinking long, I should have gone for the top model CR-2020

btw, it has the best implementation of ’Loudness’ that existed in those day.

To get remote volume, balance, (and other features I don’t use) for any Vintage unit without remote,
use this either 1st in line, or, what I do with my Yamaha, thru the tape monitor for optional use.

You MUST have the remote, no controls on the unit itself.

PS: IF/WHEN you get your 300 amp fixed, what will you do with it’s temporary replacement? Let that help you decide.
