The most successful version in non-inverting inclusion. Only high-quality components are used. At the entrance, a high-quality polypropylene, film capacitor is installed. A high-quality non-polar electrolyte is installed in the NF circuit, again shunted by a polypropylene film capacitor.
The amplifier is quite a bit inferior to the LM1875 at the very top, however, the middle and the bottom beat unconditionally. With a sufficiently high-quality source, the amplifier subjectively does not require any correction in the form of a timbral block. Any possible troubles were "caught", in connection with which, the amplifier turned out to be relatively cold, even at capacities close to maximum.
Do not connect the "-" terminals of the speaker output to each other!
It requires two polar power supplies, it also requires heat dissipation in the form of a radiator. The area of ​​the radiator can, very approximately, be calculated from the need of 20 sq.cm. on 1 W of output power of one channel.

Maximum long-term power:
68W at 4 Om at +/- 28V
38W at 8 Om at +/- 28V
50W at 8 Om at +/- 35V
