The VERY FIRST PL12D's were very well engineered, but severe mass production set in and after a few months and especially with the mk2, the quality dropped off - rattly arm bearings, inferior lid, motor vibration coming through etc. etc. I readily agree on the PL12AC though
What were the speaker choices for the 101 back then?
I'm not having any back-door anyone (can't help being a Zep fan)
The Doc will elaborate better than I, but the Wharfedale Denton (nice original not the later squawk-boxes) and Linton, Celestion Ditton 5's and 10's?, Goodmans Maxims, KEF Celeste's, Cantor's and similar and a host of other little boxes now long forgotten I remember.

Well I built my own speakers when I moved into a flat. Big concrete lined bastards with 15inch bass drivers. Stupid as it required 4 people to move them. The Sansui drove them with no problem.
Hooked up my AU-101 today. Surprisingly good sound coming out from this little retro amp. This Sansui does ''communicate'' fairly well.
It sounds good driving headphones too. I notice that I hear a very mild hum through the headphones with no music. It doesn't affect the music but is this little hum normal??
1/ is the hum volume dependent or the same all the time - if volume dependent then the the problem is not in the power amp section.
2/ disconnect the inputs, if it still hums it is the pre-amp or power supply section of the amp that has a problem, if it doesn't then the problem is in the source or the leads carrying the source signal.

With the CD player turned off, nothing changes. All the same.
With the CD player switched on. It gets worse at high volume. I've tried a different interconnect, same thing.
Possibly talking out me bum as usual, but early 70's amps weren't anything like as capable as modern ones and on some of them, a little hum was usual I think.
On the 101 though, old age is more likely to be the issue.
