60W -> 100W Texas Power Amplifier for home SUB boxes

Don’t execute your neighbor, he can do more than you think.
At that time, even the Watt calculation was real, it didn’t mean like unfortunately on today’s amps!

The heat sink below 2 BD should have mica and screw head insulator.
Next to the silicone grease!

If today’s BD transistors are metal-free insulated, then only silicone grease should be on the ribs and transistors published. It depends on what they give.

The 0.22 Ω resistor pair can be made of thin lacquered copper wire or ask for higher power pieces!
Because the full power goes into these two.

The power can be significantly increased with the secondary output of the transformer!
W = V x A
