Can anyone who remembers the Jap TV sets with two tuners help me please?

I am modifying a UHF rotary tuner (the ones with rotary dials which sometimes seized up)

Matsushita VOM 540. Also printed on the ID paper strip; F-103 661 G

I'm not looking for much detail, only need the supply voltage and how to disable AGC and AFT, i.e. do I ground or energise the AFT and AGC
terminals to disable them?

Google is as handy as a hat pocket on this, they keep passing me over to eBay. I'm hoping an ancient TV tech like myself can remember more than I. Any info very appreciated.

Thank you.

It is always denied, of course, but Google receives a lot of money for Ebay's dominance in search results and there is a lot of 'keyword stuffing' which usually leads a user to irrelevant content when links are followed.

I had no idea Google and Ebay are in cahoots. Now I understand why my search for 'Matsushita rotary UHF TV tuner' floods me with over-priced junk like obsolete laptops, plasma screens and other surplus rubbish people try and off load onto suckers like me.

And it's all legal I suppose, I don't pay Google to do my searching for me, so I just have to grin and bear it.

For the purpose of the exercise, I will put my request out over Firefox (they claim total independence) and see if Ebay sticks its unwanted guts in my face. Will report back soon.

OK, so the very first result for my 'Matsushita UHF TV rotary tuner' search via the absolutely independent Fabulous Firefox is a wonderful offer from Ebay---a bargain even; a dual band mobile ham radio transceiver.

I can email you a circuit that used that tuner, it should have all the info you need.

But you'll need to unhide your email address or email me.

Fantastic! Thanks Ian, shall open up my email address very soon.
