AB763 PT Question

[mikeboone]

I built a single channel (normal channel) 2x6L6 AB763. I used transformers that I just happen to have in my stash.

The PT is a Heyboer 320-0-320, 150mA, similar to what would be used in a Bandmaster.

The OT is a Hammond 1650P 60W.

I am using a single 15" JBL D130F.

My question is... If I replace the PT with a higher current device, i.e the 200mA originally spec'd, will I gain any volume or clean headroom?

The amp is pretty loud and breaks up nice like it is, but I play with a big band with a 4 piece horn section and any more volume I can get out of this guy would be nice.

I am just asking advice before I commit the change.

I attached a pic for those interested.

Most likely not, unless the PT is being extremely overtaxed, which is doubtful.

A better solution might be to put higher voltage onto those 6L6's, as in the Super 5F4.
