Default Tent shunt

Hello,
Tomorrow Tent shunt supplies will be installed by a technician who already made some other changes in the original design used in the 20 watt Hiraga amp belonging to my friend.
We will see.
Greetings, Eduard

Hello,
The input stage of my friends Hiraga was changed in a way that I will kind of behave like a single ended amp. The output power is reduced 50 % by this modification.
My friend will surely keep me informed about the improvements the tent shunt did bring.
Greetings, Eduard

A better solution for the psu.
Do NOT use the bridging MKPs. Remove! Or replace by 5 - 6 100F OR 220F OR 470F.
The ground RCA - board, I remember, is to alter.
And something others.
Your Cary Valves do sound MUCH better - do have the MUCH higher potential;-) Trust me;-) Change your speakers! And sources. The Hiraga A is a four-stage-complementary-parts-pp! Impossible to get a clean clear sound. NO CHANCE! That is a rumbling, roaring, noise-amp! Have built and tuned some;-P

And remove the copper-RAILS;-! Replace by 0,8 mm or 1,5 mm solid core.
Replace the litz-wire. Use solid core or coated litz-wire. MAX. 0,8 mm.
