Hello folks,
I have in hands a TV amplifier which uses an 8877 tube which I'd like to
convert it for 144Mhz.
Unfortunately I dont know what the original frequency is, and which
parts I can use for the new project.
I placed a 2k resistor from plate to ground, and the MFJ antenna
analyzer on the output, I could get a dip of 1:8 SWR near 86Mhz, so I
take a guess that it might be for VHF channel 6.
Do you think it should be possible to convert it to 144mhz saving some
parts? The shorting bars looks nice.
A couple of pics of it may be found at:
