Japanese Hybrid TVs

While watching some restoration videos from the US on Youtube, it seems there were a number of valve Japanese TVs available in the US. So I wondered if there were any imports to the UK ? Sets for the UK would need more re-design work, so did the manufacturers go all solid state from the off ? I know early Sony colour sets used valve EHT rectifiers but does anyone know of any hybrid designs by any Japanese makers ?

I think Sharp had a small screen hybrid CTV.

Biggest problem any Far Eastern manufacturer had was either getting around the PAL patents or paying a premium for licencing. The US was a ready market by comparison.

Back in the early seventies I had one on rental.   It was an excellent receiver, always displayed a really good picture.  Can't  remember if it had a full spec PAL  decoder or simple PAL-S.

I can’t remember either, I only saw one, it had I think a frame fault but could be wrong. Whatever the fault it was just a valve but I had to order one specially. The picture was excellent, this would be late 70’s, no idea how old the set was at that time, presume it was early 70’s.

Hi Frank,

                    The 16" Sharp colour  set I used to look after was bought for rental in 1973.  The plastic cabinet was finished in black and white and looked quite smart.  I do remember it had a delta gun CRT which was branded as Sharp but was most likely made by Toshiba. After giving the set more thought I do remember it having a Philips glass delay line in the decoder.   After 1971 or was it '72? Japan was allowed to export small screen CTVs into the UK with full spec PAL decoders.

I'd forgotten about Teleton PAL-S sets, I asked since I'm always on the lookout for colour hybrids from various sources, which are very rare now, but usually discount any of the Japanese makes, but it might be wise to investigate when they come up.

There is a thread on UKVRRR from 2006 on the Teleton, it includes a description of the decoder.

This is the thread, post 18 as the description.

The Sharp CTV referenced in an earlier post I think the USA term for the 12 pin based valves was Compactron.

Yes, they were made by the General co, before it was taken over by Fujitsu, then becoming Fujitsu-General.

For their day, they were very well made sets and pretty reliable.

(All except mine that's lost its colour and defies all logic to repair!)

Main market for these/similar sets was USA, they were supplied to Packard-Bell and badged accordingly. The 'odd valve' line up to us are just common or garden TV valves in the USA, just like they have little knowledge of the likes of PCF802 and PCL85!

When I started my first job in 1970 it was for a small family run business, and he used to stock sets made by Crown (although that may just have been a brand name). These were small hybrid portable sets I think just the timebases and possibly the EHT. I think these may have used Simple PAL because I was never really impressed with the pictures, colour rendition was decidedly poor. I think they also had a tint control. Maybe they were modified NTSC sets.

Santo brought out their 16" CTP370 "Colour Deluxe" model in the early '70s. Employed familiar Western European valves throughout except for the 3BS2A EHT rectifier. In this set the valve rectifier had been replaced by a stick type in the past.

Valves from memory are PL509 "Horizontal Output", PY500A "Damper", PCL805 frame, PCL86 sound, 3x ECC82.and 2xPCL84.

Although marked, "Colour Deluxe" it's simple PAL.

This example is in need of refurbishment, yet it worked when I ran it up a few years ago.
