QUAD II Stereo Set Up

[dragonstar]

Hi There,

I'm hoping someone may be able to give me some advice?

My father died recently and I was allowed his pride & joy.

His wife said she wanted to keep the CD deck, though when I arrived everything had been taken apart & things "moved".

It's a little odd I think something else is missing, but at the time everything was so painful & difficult with his wife, I can't remeber what should have been there.

With the number of shelves that were filled I seem to have something missing.

Turntable & pre amps were on shelves with the CD deck, the quads on the floor, so now I'm wondering if there was an equaliser or something in the set up that she has decided to keep without letting me know as there are 4 shelves, I'm sure I remember them all being filled?

Sorry if I haven't added to the right area and not entirely sure if this is the right forum, so if anyone can point me in the right direction if so that's be great also.

Thanks Jess

Maybe the matching tuner?

if you connect the pre-amp to the power-amps via the umbilical cables and then the power-amp to some speakers 20 watts plus of the same impedance ( there will be an impedance set on the power amps) you should be ok to connect the radio and turn table.

BUT IF THE AMPS HAVE NOT BEEN USED IN SOMETIME ( A FEW MONTHS ) YOU WILL NEED TO FIT AN 80WATT LIGHT BULD IN TO THE MAINS LEAD IN SERIES LIVE SIDE IN A LAMP FITTING AND RUN THE AMPS FOR 8 HOURS WITH NO MUSIC SO THE CAPACITORS REPOLARISE THERE DIELECTRIC STATE OR THEY WILL BURN OUT (and it will cost you lots for money to repair this)


so don't just plug and go..............please!

A few months??? 8 hours???? What - do you work for an electricity reseller? Or a witchdoctor?

8 hours is minimum or you will burn holes

in what?

As Dave mentioned, it might be the matching tuner which would be a novelty, but hardly worth running, as is the preamp. The real bounty is the power amps.
As Pointy mentioned, the preamp connects to the power amps with 2 umbilical cords. These are really fragile at the power amp connector end and wires can become disconnected and exposed easily.
One point to add is that the preamp must be switched to "stereo" for both amps to power up. I am assuming a stereo setup, although some of these were sold as mono with a single amp.
I think that Pointy was being a little pessimistic about the caps needing re-polarising. It may take some years without power for them to become unpolarised. However you may not know how long the kit has been out of use...

in the dielectric sheet

The point is that if an old 'lytic has been idle for a long time, the leakage current can be high. This in turn causes heating which can, at worst, blow the can.
By ramping up the voltage slowly ( a 2-stage ramp in this case), the cap can re-polarise and the temperature rise minimised.

some slightly more considered words on the subject...
