Hi all, I've found this little black and white all transistor TV last year, Japanese and destined for the US market. I've powered it from 12V DC and it worked first time ! However when I connected it to a CH4 VHF modulator, I noticed there is distorted audio, probably nothing serious, the speaker is OK, however does anyone have any idea of the age of this TV or any service data for it, there does not seem to be anything I can find. It looks rather difficult to work on as well !

The set is apx 1966. Sams makes the manual BUT dont get it from them ! Way
overpriced for a crappy PDF or photo copy. Working on them is not as bad as it looks.
On old Pannys removing the red screws will get it workonable. PC boards usually
fold out also. They were best built of the Japanese sets IMHO.
For audio plug an ear phone in to check the speaker. If not that usually a bad
electrolytic or the output stage is toast.
