Hello All,

I was hoping somebody may have a circuit diagram or any information on the Pye TS6 solid state radiogram. The chassis is very similar to the Pye Black Box ( the later one with changer not single play.)

If it was valve it would be going by now. Finding transistors is a nightmare.

Regards
Vic

Hi Vic
I've got a TS22 schematic....not sure if that's any help mate? Cheers George

Thanks George,

Don't know if that is similar but you can email me a copy and I will check it out,

Cheers
Vic

Old post I know but I've just had a TS6 pass through my hands.

The TS1 circuit, available on Kevin Chant's site, is a starting point. But the input select and audio front end is different.

It uses Fairchild silicon planar PNP transistors in all locations bar the outputs which are the same as the TS1, i.e. AC128s.

It's doubtful if you will really need to replace transistors, they rarely fail unless they meet with an accident. But, BC557s will replace ALL of the little black silicon transistors. Electros are more likely to need replacing.

A strange wrinkle with this model is the input select arrangements, which are bizarre. As a result, the radio only plays through one channel, it's low level in the other.

If this is your fault, well, as they say "they all do that"! Go figure....

I traced the circuit on the one I had, trying to find out why. If you need it I can send my hand-drawn sketches.

That input switch is a bugger to work on.....

Oh yes,the RF gain of the radio is a little less than you'd expect. Early silicon planar PNPs (as against NPNs) are not exactly hot performers. A set of modern BC557s should improve things.
