dh109

thanks

X119 = UCH81
U119 = UY85
B109 = UCC85
W119 = 10F18
DH109 = UABC80

Must have come from an AC/DC set.

The difficulty with using these valves for home projects is that they have nonstandard heater voltages, since they were designed to be used in a 100mA series heater chain. The W119 is an RF pentode with a 13V heater and could be used to build a one valve radio using one of the many circuits available (e.g. here). A 12V supply should be adequate for the heater. The X119 could be used to build this MW microtransmitter if you can find a 19V heater supply.

If you can find a 40V heater supply you could use the 10F18 and DH109 to build a 2 valve radio, wiring the heaters in series.

Or you could flog or swap them for some E series valves with a 6.3V heater.
In fact if you fancy it PM me I could do with some U series valves for stock and have loads of E series stuff which would be good for experiments.

GEC BC402 just add an N119 (UL84)

So... build an FM/AM radio! For safety use a 240V iso TX and a capacitor dropper for the heater chain.

thanks for all you help.

what one should i do as there are so meny of them and i have little nolage in valve eletronics.

thanks chris

i fogot to mention that that is the set they are from as i got givin it but the case was all smased up.
