Re: [CQ-Contest] Modify AL-1200 HV Power Supply by adding 2 capacitors & bleeder resistors

[Tony Brock-Fisher via CQ-Contest <cq-contest@contesting.com>]

I did a similar mod on my AL-1200. If you read the original QST review 
you will note that some of the early ones had incorrectly wound HV 
transformers - mine must have been one of those, as it never got over 
3200V. I added one filter cap and bleeder to bump the rating of the 
capacitor bank to 9x450=4050V, then changed the primary tap on the 
transformer. I now get 3600V on the HV. This gets the output and gain up 
where it should be.
It has run this way for a decade.
