Quad II/22

Postby laurencefoulds » Fri Aug 09, 2019 6:55 pm

Hello all.

This is my first post here, so please be kind.

I have been left by my father a Quad II/22 amplifier complete with an AM and FM radio plus a Goddard 401 turntable with an SME arm all enclosed in a tasteful (!) sixties wooden case. It used to be have a pair of Leak speakers, but they have been lost.

The whole thing hasn’t been switched on in 20 years and I know the AM tuner doesn’t work but I don’t know whether anything else does. As an electrical engineer I am aware of the delicacy of 50 year old wiring so I would like to get it expertly serviced and won’t switch it on in case it causes damage, but as far as I am aware it all worked - apart from the AM radio. Can anyone recommend a suitable service engineer? I live in Southern England.

I would also like to know what speakers - old or modern - would best work with the refurbished system?

Thank you all
laurencefoulds

This is a forum about music recording rather than vintage hi-fi, so you might get better answers on a different forum aimed at vintage and collectors' hi-fi. However, there may be a few contributors here who can help...

I would suggest that this is all very collectable and sought after stuff, commanding good prices even if non-working, and very good prices if working!

I presume your spell-checker corrupted Garrard into Goddard... ;-)

I can personally recommend AmpLabs for servicing/fixing/refurbishing you Quad II gear. He's very experienced with those valve amps and I've been impressed with some work he's done for me and for several friends over the years. He's in Worcester, but it's a nice part of the world for a weekend getaway if you fancy delivering in person, or there are couriers!

http://www.amp-labs.co.uk/contact.htm

Of course, there are plenty of other companies refurbishing old Quad gear -- including the Quad company itself. And many others offering to buy old Quad gear regardless of condition. A google search will provide alternatives...

The Garrard 401 will probably need a good service/refurb too. Bearings, idler wheel and motor will all need attention, as may the sme arm. For that I'd recommend Peak hi-fi in the peak district. He is a specialist in refurbishing and upgrading these classic turntables, making many bespoke new and improved parts. I had him completely re-engineer my dad's old 301 with a 12-inch SME arm and it is now a truly stunning turntable -- visually and sonically!

Again, a google search will provide alternatives.

Veeeeery nice!
I picked up a couple of Quad 11's at a boot sale, they looked a bit dodgy, wiring wise, but when I plugged them in they actually worked perfectly. I'm not advising you do this, maybe try these people...

I've not used them myself, but they may be worth a try, depending on where you are.
Have you got all the Quad connectors? if you haven't there are folks like this who will make them up...

I've used these people and they are reasonably priced.

I'd go for a pair of vintage Tannoys in this system, they are very efficient, and will make the most of the Quad 11's, something like a Cheviot, I used those with my Quads, they are quite affordable, or Lancasters if you want to spend more.. Amazing stereo imaging, just a fantastic sound, even by today's standards.

Spoiler: Mike Solomons of London Sound happens to be my cousin.
Having said that, he is quite passionate about British High Fidelity equipment. And he is an excellent engineer. Over the years I bought all my High Fidelity (NOT HiFi) from him; including Quad.
Apart from that, I can warmly recommend him.

The good news is that the expensive and difficult to replace components, the mains and output transformers plus chokes, will be fine, as probably will be the valves. I would definitely go to a specialist: one of the techniques for old valve equipment is to slowly wind the voltage up using a variac. You can also reform electrolytics, but your repairer is the one to diagnose and work out what to do.

For speakers, I would avoid anything old (or vintage). Like pianos, speakers don't improve over time. I would go for some Spendor, KEF or ATC floorstanders. Rather un-intuitively, larger speakers usually need less driving than smaller, bookshelf types.

Yes, older speakers can be a pain, but if you budget for repairs, and go to the right people to get the work done you should be fine. A friend had his Tannoy Cheviots sorted out by a chap in London who was very good indeed, that's all he does.
There are specialists dotted around, for AR's Tannoys, JBL's etc etc.
Another friend had his Heybrooks re-coned by Wembley Speakers, they did a good job and they sound as they should.

Tannoys of that vintage can be repaired fairly easily as the parts are still available and everything mainly bolts together so that you can remove a cone or diaphragm without any special tools. Hopefully this parts availability will continue under their new owners.
