Working on my MKll. Trying to figure out the size of a cap. Not being a real tec i get confused on capacitor numbers some times. It reads 150 x 100v. My chart jumps from 131 to 151. If i am looking at it correct is it 15pf =.0022uf? Jim/238

Huh?
Is this an electrolytic cap? A ceramic disc?
Just not getting the picture. How it's marked could be helpful. A pic even more so.
Maybe.

It is a ceramic disc. Markings are 150 x 100v. I have another MKll that was rebuild back in 2009 an they install a new 304 /c12. They added 2 of these across the 304. My problem is when i tune the radio the 304 tightens up all the way. The power is still going up, it is at 2 watts when it tighten up. Thanks Jim/238

So, it's in the transmitter.
You didn't say.
The capacitor is 150 picofarad (pf). If that one goes bad, the 304 will tighten all the way before reaching a peak setting. Some capacitors may be marked in the same way as the color codes of a resistor, but with three digits. Where a 150 ohm resistor would be marked brown/green/brown, a capacitor may be marked "151" meaning 15 with one zero behind it. Any voltage rating over 100 Volts is okay.

You are never too old to learn. It took me awhile to figure out my miss figuring. All the 3 numbers on my chart ends in a number. But if the number on the capacitor ends 0 that is it real value. Thanks Jim/238
