Unknown valves
1 Attachment(s)
Hi,
Can anyone help identify what these valves may be. I got them in amongst a box of b4 base triode valves I bid on in a sale. All the markings have worn off. If I can identify them I'd like to use them for something maybe. Thanks, Mike |

Hello Mike
If pins 2 & 7 are missing on the two in the middle, they're probably ARP12 with the metal coating removed. Have a look at the Valve Museum picture: http://www.r-type.org/exhib/aaa0572.htm |

Here's a view of the pins.

Re: Unknown valves
Hi,
Centre spigot size might suggest Mazda octal, and if so with pin 7 missing these could be SP41/61. Height is similar. Large one to the left in the first picture reminds me of Marconi/Osram KTW61 or KTW63 Cheers Rich |
Re: Unknown valves
Can just make out VR 14....? On one of the smaller ones.

That's what I was just looking at, looks like it most probably is that.
Was thinking this may be the bigger one. |
Re: Unknown valves
How about VR116/CV1116/6F32. RAF stores ref 10E/266
