Quad Help!

[spendorman]

I bet the Quad lamp is loose, pushing buttons just shook it a little making contact. Take cover off 33 and check bulb is screwed in fully.

As for the other 33 problems, a bit of a mystery. CD should work into Tape replay and Tuner input, but tuner input may be too high a sensitivity, think it was particularly sensitive for the FM3 which had little output, possibly about 100mV?

No output from the other radio input at all, unless it's very very quiet.

I thought about that. It's a very tight squeeze to get to it though. I don't feel confident enough to move other bits just to get the light working. But I will dive in again and try.

I am beginning to wonder if something else is loose inside. I might open it up again and push a few things just to make sure everything is in place.

Has the 33 been out of use for a long period?

[symon]

I don't think so. It's been sat on my floor for a month or so. I'll have to check about what was use it had before that.

Only thinking that the selector switch contacts may have corroded, but its not that likely. My 33 was in a loft for about 8 years and was still OK.

Have a look at the pliug in boards inside the 33, carefully take out and look at the contact area. Don't use any abrasive to clean them though. Put boards back in and try again.

Just been looking at the service supplement for the 33, it does say that the sockets for the internal plug in boards

"have been known to cause confusing symptoms of erratic operation, attributed to other factors such as pushbutton switches, solder joints etc."

There is a cure, I can scan this in if required. Think it would be worth tying what I said before, removing boards checking and putting back in, before doing anything else.

Hmmm - took out the removable cards inside. They all look fine to me. The connections look clean enough. No change. Using the Radio 1 input, tiny sound on the stereo button, fuller sound on the Mono buttons.

Would photographs of all the removable cards help?

I will scan in the part of the service supplement about the contacts
