Marshall TSL 100

Hi


This TSL 100 I am working on has a very high plate voltage. Without any power tubes in, the plate voltage reads around 535V. With the tubes in, the voltage drops to approx 505V. Is this plate voltage acceptable. How can I bring down the plate voltage. Please assist.


Thanks

There should be 525v HT off load and about 510v running. These vary with AC supply as much as 10% so I would say that 505v was about right.
