I've previouls mentioned my TV22's looks like I need to add the following:
1) TV32 - Restored/working last time I tried a few years ago
2) TV62 x 2, one basically working, the other needs restoring.

@Panrock Do you want serial numbers ? If so I will try and get to the sets (incl 12/22's) and advise.

TTFN,
Jon

I have two TV22F sets. But the TV22F is not what you asked for in the initial post...
If you are interested I can look up the serial numbers for you.

Regards, Roland

Hi Steve,

The TV22F is ccir 625 lines fm sound with eq80. I will look up my serial numbers and I know of another few in existence. I might have also numbers of these as well. In one of my sets was also the original schematic. Quite happy with that because these things seem to be quite rare... Up to now it is the only part of documentation I ever found.

Edit: is there any information in the serial number about production locations for example?
One of the numbers is 103/00145 that set is also in a topic here...

Regards, Roland

Thanks Roland. Is that an FM tone correction time constant of 80 µs - or it used EF80 valves? It would be most interesting to see the schematic. Thanks, Steve

The EQ80 is an FM detector.

Thanks for putting me right there Ron. It would be interesting to know the TC none the less. I believe UK FM radio used 75 µs and UHF TV 50 µs. Steve

Hi Steve,

I've uploaded the TV22F schematic to https://elektrotanya.com/ some years ago but I've attached it here to this post now.

The two Bush TV22F which I have:
103/00145 (mentioned in #85 and also described on this forum)
103/00017

103/00036 (known to be in the Netherlands, but is modified. I have thought on buying the set back then but the PL33 was replaced by a PL82 or a 84 and the PZ30 was replaced by a PY83. AQlso the ferrite core war removed from the tuning coils, there were trim capacitors placed instead over the coils.

103/? Another Dutch collector has a TV22F set, but I don't know the number.

So at least four of these sets are in the Netherlands. Serial numbers are quite low...

Regards, Roland

Hi,
I have 3 BUSH TV 22.
One with the Pico-valves, one with the Noval-valves and the rare
F-version for CCIR!
Sorry, but I will take some time to send you the chassis-numbers!

Regards,
German Dalek

Hi Roland,
This is very intersting, my tuning ferrite cores are broken, received them inside a
little bag, when I picked it up from Amsterdam.
Because I see some trouble to glue them (all parts are there), I should decide
for tuning caps, too.
I really like to get some informations, to copy the change.

Regards,
German Dalek

The only information I have are the attached pictures from the set. I hope it helps. These are called Philips toltrimmer in Dutch.

Many thanks Roland to share these pictures!

These tuning caps are wellknown in Germany and you will find them
mostly in radios.
The original construction is very flimsy, these cores are easy to crack when
tuning the set.

German Dalek

Hello,
thank you for the interesting list.

I'm in possession of a TV22F with s/n 103/00197 in good condition which should make it the 6th known in existence, right

I've had it since early 70's and used it for watching Denmarks at the time major broadcast channel.
It's been on display only since the 80's and I'm hesitating to wether powering it up or not. I've read some useful tips here in the forum and will do some checkup on the set later on.

It lacks the power cord which has been lost during one of our numerous relocations over the years, so if anyone have one to spare I'd be happy.

Höllviken is in the south of Sweden btw.

TV32 120/08541 Working generally as standard.

Kind regards,

Peter
