Mate of mine's brother in law just purchased this Pye 3-in-1 for $450, which I gather is from the mid to late 1960s. I'm not into TVs myself, but this appears to be a rare unit these days and it's in very good condition. Even came with original purchase documentation and owners manual:

That's a lot of money for one of those. Wow.
I imagine he is a mid century furniture collector and the house is decked out in mid century items.
The trouble is vintage TVs can be very temperamental things to the point where you think about having wing nuts holding the back on.
So you really need to know how to repair them. This is the problem I have been battling for years . If its just replacing paper caps and Ecaps than I'm ok with it, but if needs fault finding ,im stuffed!!!!
Fault diagnosing on a TV with a meter is an art on its own.!
Im 50 now and feel I should be able to do it by the time I'm 100!
I seem to be ok with Radiograms and turntables though ,,,I just finished a 1177 and gave it a full recap and all went well.

The other 3 in 1 pye that comes to mind is a very nice set made in 1959 and the identical set was sold under the name STC too.
I had a very nice one ,but unfortunately it could not come in the last house move with many other old Gems I had.

I don't have a feel for the value of 3-in-1s from the 1960s as I don't dabble in them. This one is in pretty schmick condition. Definitely a looked-after item. An ad in the SMH in November 1965 prices the 19 inch model at £292/17/- which the Reserve Bank says equates to around $7,950 today.

I don't know the reason for purchase. May be a nostalgia thing (family had that model when he was a kid, perhaps.)

There is a mid 60s Teak parker lounge in the corner of the pic, they are highly prized by mid century collectors. I use to sell them and they bring about $3000 for a 3 seater and 2 chairs.
I lost count of how many I restored for people.
Hot property!!! The last one I sold was about a year ago and now I have none left to restore or sell,,, wish in did!!

Whether it's worth restoring really depends on the condition of the CRT.

Later 60's sets used poly caps rather than paper and were quite often not a terribly difficult repair.

After a good visual inspection use a dim bulb tester in series with the mains to see what happens when powered up. (you will need fairly high wattage globes for a TV).

For a fully-loaded TV chassis, those bathroom heat lamps are the go.

I probably would have been crazy enough to pay $450 for this. It looks to be in fantastic condition !!
Perfect mid century styling in a Rosewood cabinet.

What I really want is a HMV Stratford Y1 D3. It's a 3 in 1 from 1967

I was thinking para floods but heat lamps would be even better. I'll have to go and buy some now. Every day is a school day.

1966 Pye Chancellor unit, I have the television in console in awesome condition, I paid $25 for it,and unfortunately it is more desirable than the monster I see there,your mate paid $450 to much ,I knock these back all the time, but if ppl will pay that sort of money for them I might start keeping them lol,they are chipboard under that veneer and moisture will swell and crumble them, in saying all that it is not to bad condition ,should be polyester caps too, my Chancellor is on radio museum if he wants a look

your mate paid $450 to much

Value, like beauty, is in the eye of the beholder. People throw lots of dollars at "empire state" radios. I consider them ugly, and thus of no value to me.

Personally, I wouldn't pay anything for any vintage TV. I have zero interest in them as collectables or restoration projects.

Then why post in a vintage TV forum ?

With the topic being about a vintage television, posting here is the most appropriate place.

I'd love two or three of the very early ones but unfortunately I do not have the room. One of the first 10 channel AWAs would be lovely, though my main interest is radio.

Just a note here regarding what is referred to as chip board.
50s TVs were ply, Around 1963 TV cabinets were made from chipboard, EG so is, parker furniture, chiswell, danish,, all chipboard. There are many reasons they moved from ply to chipboard , one is cost ! Two is its adhesive abilities, three is its dead flat! Those 3 points make it excellent for veneers. Remembing a veneer is the most beautiful part of the timber and has been selected for its beauty. You can not get a beautiful figured cabinet if it was NOT a veneer.
Chipboard is like anything else in this world and has degrees of quality depending on its glue and where it was made.
The exception to the list of items above was Kriesler stereograms from the 60s .most are built from " baltic pine " fully imported from Europe. Baltic pine Ply is extremely expensive even today due to its strength and excellent sound qualities!
Beauty is always in the eye of the beholder....
