I noticed the new power supply schematic has 2 2N3055 power transistors in parallel.
The original schematic only has only one.
Is the "new" power supply also limited to 3A or is it 6A? (assuming the transformer & heatsink are ok)
If more than 3A is possible, does one only has to change the setting of the current trimpot?
thank you

hello,
I would like to replace R7 with a shunt resistor of 0.0075 Ohm,
I assume this will have an effect on R17 & R21.
P2 should stay 10k (I already have this one).
-How can I calculate the new resistorvalues?
-R7 limits the max possible (short cut) current in the circuit, maybe I could increase the resistors at the 2N3055 output to ie 1 Ohm to compensate for this?
thanks
