This early SS Colt is battery only. Does anyone have a circuit or other information?

Have a look at the following link. It is on Steve's excellent site: 'The New Zealand Vintage Radio Project' (I hope he doesn't mind me using the like to answer your question). www.vintageradio.co.nz/model/bell/all-transistor By the way, did you post a photo of the set (as your question implies you have) as I am unable to see it.

No, no photo. I was aware of Steve's site, but i wanted to know what value the volume and tone pots were as these had been changed in the set i have.

Thanks,but i note the MK 2 circuit shows 100k for both pots.In this set the vol pot is 100k and the tone 10k.
Perhaps not related, but a strong signal causes 'overload' and instability.

Sorry, I recall seeing this post and I'm sure I meant to reply to it. I'll check mine and another I have access to and let you know... in the meantime a couple of quick questions on your one - what is it's serial number, and does it have a push-action on the tuning shaft to trigger a dial light? Another collector recalls this feature on one he saw many many years ago - Mine and another that I have seen do not have this. I'm interested to know if it was an early feature that was removed or a later addition. The models I've seen without it have serial numbers as follows:
A26780
A26955
This battery-transistor design seems quite an interesting take on the Colt, and I would hazard a guess that this is by far the rarest of all Colt models - so it can't have been very popular? Possibly because its a mantle radio masquerading as a portable? Or maybe they all got used as portables and the cases got smashed so they were all thrown out? Yours is only the third one I have heard of, although I'm sure there are more out there hiding.
Cheers, Steve

Update - both pots in mine are 10k although the tone control appears to have been replaced with a switched one with the switch guts stripped out - either that or Bell got a deal on switched pots and stripped out the switch mechanism to use them for tone controls.
Cheers, Steve

SN A26834. No lamp. Interestingly, the tone control on this set was also a switched pot with the guts removed.
