GEC BT452 |
|
NOTES | A typical set dating from the year I was born (though I think telly has
survived somewhat better).
The set seems to have been sold in three versions, starting with this one (basic 405-line), a dual standard 405/625 plus a third almost like the second but without the UHF tuner. Although this particular example is the 405-line version, additional holes required by the later versions are present albeit blanked off. The timebase also has seperate 625 and 405-line line-hold controls. |

SERVICE DATA | Service data is spread across three "Trader" service sheets (1617-1619), copies of which were obtained via the B.V.W.S. |
CURRENT STATE | We have sound and a raster. However the line timebase frequency is wrong
; I suspect someone tried to convert it to 625 line as it runs too fast.
However it still syncs to a 405 signal, only to fractional multiples of
it, if you can picture what I mean. Thus as you adjust the line hold you
get discrete notes from the line timebase - eat your heart out Rolf Harris! |
WHERE FOUND | July 2003 Haydock Park event for a tenner. A sensible price unlike a lot of the other stuff at the event. |
The main reciever PCB. | Suspicious number of replacement parts in the timebase panel. |
