This video was taken a couple days ago.
Here I show a pa I helped modify over 24 years ago. One that over the years I corrected with the help of others.
I forgot to add that a fuse is in series with the soft start resistor.
Pa originally had 5500 vdc on the plate.
Plate voltage mter is in series with the b-side of the plate bleeders and has a resistor in parallel with the meter movement.
The second pa I built lacked room for components capable of 100 percent duty cycle operation. Blower was also too small in that pa.
I did have help adjusting the neutralization cap in that pa, over 11 years ago.
This pa is up for sale for 55k, 80-15 meter operation. Videos will be added if ever sold. Not holding my breath
