He got to try out lots of gear.

Highlights included the Dalek-like KEF 105 speakers, but the Quad amp-pre amp combo was the most enduring part.

Nice. I think Kef are still about too.

As well as the Quad I've got the Thorens record deck to look at, plus a Sugden tuner (valve I think) and a Technics dual cassette deck.

My Dad liked his audio and the Quad was the pinnacle of his purchases IMHO.

For sure...

Hooked the Quad up to some speakers today and fed in a very low level signal into each channel one at a time:


Both channels seem to work great, so I think I'll move onto the record deck next :)

:yay2:

@rubber_jonnie, you need some Quad ESLs to go with that amp. Some nice retro radiator speakers :)

You'll probably need a new drive belt for the 125. Thakker.de do the best although there are some cheaper belts available. I change mine about every 12-18 months. Luckily they are very cheap. You'll know it needs changing when 45s are realllly slow :D

Has it got a fancy tonearm like an SME? I bet it has and I'm envious already :D

@chronicthehedgehog For your enjoyment here are some photos:


I have discovered an issue though, and that is that there are 3 bolts that run through from the main deck to the metal substructure. They have rubber bushings that give some softness to the suspension, which is 3 large adjustable springs (The big white knob). I found one rubber bushing to be missing:


I've pulled one from another mount and I'll see if I can buy some or even make one myself. Finding a nut and washer should be a trivial task. This is what is missing:


It looks like the nut worked off over the years, but somehow my Dad didn't notice. I think it is a Nyloc nut (Or some sort of locking nut), so it really shouldn't have fallen off, but I will use a drop if threadlock when I reassemble it. I'll use threadlock on the others at the same time and I'll re-level it using the spring adjusters.

BTW I already have a replacement belt :)

It is interesting to see that the electronics of those days was a lot more colorful...

Very nice construction, reminds me of my school days where we learned to tie the cables together this way...
