The brown stuff on the caps is not electrolyte. It's glue, used to secure the large components and their solders from vibration. Very common to see, especially in items of japanese origin, and can be hard to shift. Martin

Happy birthday, Andy ! Martin

Thanks, sounds like a good fix in the cases where the plastic collar breaks. Not a problem I have ever seen, though. The faulty ones, I have dealt with all had the commutator deformed by over current after brush fails and I found no solution to this other than locating a replacement motor. It's usually diagnosed by a frozen motor, alternatively

I really would like to get rid of the large ceramic resistor but with no original dial lamp in sight, an alternative to the large ceramic resistor and the heat it produces would have to be found. The large resistor looks completely out of place, it emits a lot of heat, surface temperature measured in at apprx 160deg C using an IR thermometer, and I

Geoff, What's wrong with the transistor ? I would think that any good FET should work, it's not particular high frequencies or high power. Martin

Yes, it determines record size by lifting the record and sets the starting point accordingly. A light weight record is presumably a 7inch, which it will be able to lift. It can't lift a 12". Martin

It seems it doesn't detect the record since this is the standard no-record-present reaction. Martin

There IS a servo motor and a belt for tracking. Transport to the lead-in groove of a record and return to parked position is done by mechanics driven by the platter motor and the sequence wheels but tracking while playing is done by optics/electronics/motor/belt/wormgear/plastic wheel/steel thread. Press play; -Does the tonearm move to the lead-in groove

That's right. Last time I spoke with him, he was no longer active collecting. Actually, a couple of years ago, Jan Thogersen kindly allowed Beoworld to use his photos for the product guide. Martin
