Default Using 12 EL519 for T8

Dear Sir,

I am just thinking if I use 12 EL519 for a Transcedent T8 instaead of the original 8 inorder to increase the power. Should I change the spec for the fuse? I am going to use two 300VA transformers in parallel to deliver 135V-0-135V. (The origianl deisgn was 120-0-120 but I can only find the 135-0-135 availble. I will change the bias resistors)

You'll end up about 15VDC too high so I suggest you put a dropping resistor between C18- C20 and C19- C21 respectively.

Is that a 500mA Slow Blow fuse?
If so, go for the next one up if you see the fuses blow for no apparent reason.

Cheers,

Default Va

Doesn't VA stand for Voltage Ampere, which means Watts?

Has not really anything to do with the actual voltage you get from the transformer.

Am I rigth?

Yes, only that's not the problem.

The point is that the original xformer is 120V-0-120V, not 135-0-135V.
