TSSA - The Simplest Symmetrical Amplifier

[Salas]

Intended speakers have a lowest 4 Ohm valley at power range 200hz-800Hz, but 95dB/1W, has the mojo for those?

Salas...

Install ALF16N16 and ALF16P16 and reduce RF and RG to 499R and 49.9R

C12 and C13 should be 220pF.

To for the lower gain as your speakers are very sensitive....

[Salas]

My speakers are sensitive but my preamp ain't, its a buffer...

But if your source can drive it to 2Vrms it should be ok. Else use 1K and 49.9R

Ask Joachim about powersupply as he has sensetive speakers too...

Phonographic source, low mc cart, not helping. I will use it as 26dB and see how it goes first. SSA 26dB Sziklai p2p A/B 175mA bias source follower proto was boom rocking them.

[Salas]

TSSA may do that too, lets let it speak first.

A cap multiplier was madatory on my build. Otherwise there was a small hum. I think that behavior is typical for class A amps with low open loop gain. See the JLH 10W.

Sounds like horn system!?

Boom rocking ? Negatively???

If it will do that I will multiply the snap-in F&T with a cheap slug then, TIP3055 maybe. So it will not oscillate or something. Yes?
