Can anyone enlighten me on what the equivalent of a CV1510 would be as I have read a few pages on here but there seems to be no equivalent.

Regards, Robin.

The CV Register entry says replace with CV309, which is allegedly a QV04/7

Thank you.

I was hopping for something I had in my other sets to use as a test valve. Hopefully these are quite cheap and easy to find.

Regards, Robin.

They're a small VHF bottle, used in various bits of WWII-era military gear (such as the Wireless Set 62) and some of the first VHF two-way civilian mobile radios.

In due course they found their way onto the surplus market and - being cheap - were often used as output-valves in some of the no-name 'kit' 3- or 4-valve 'midget' TRF broadcast-radios that were popular in the 1950s.

I guess that they were - as a somewhat obscure VHF tetrode - cheaper on the surplus market at the time than the more-usual 6V6 !!

thankyou all I was hoping I could use a 6v6 as I have a couple spare.I will have to advertise for one as the set I need them for is a bit of a mess but I like a challenge.

Currently there are a number of QV04/7 available on e-bay. Also, I have one here which is available.
