Sinclair mtv1

[jr_tech]

This is what I believe is one of the varactor tuning diodes in the Sinclair MTV-1 VHF tuner section (pictured above)... it is in a TO-92 style case with no markings on the flat side, just 3 color bands on the back. (I painted the red on the top for identification in my previous post)



Apparently the tuning voltage in the set can go as high as 31 volts.

Identification and/or substitution recommendations needed.

Thanks,
jr
