Thank you TiefBass,

I don't have a true TS100 schematic, BUT a TS100 is identical to a TS90 (schematic attached) with a different output stage (section attached) and a higher PS voltage (45 V instead of 32 V)
Cheers

Best thanks for this schematic. About post #66, #36 and #40 there are also amp models with RCA's germanium power devices 2N2147 and 2N2148.

But the TS-90A (TS 90 A TS90A TS90) is also an interest amplifier

Default Leak Stereo 30

I may be wrong, but I haven't seen mentioned what seems to be the first Stereo Quasi Complementary amplifier ...

Default National Panasonic SG 999

May I add this japanese music center with disappearing turntable.
This set has an EV-like output stage and all germanium transistors. Nice looks but, unfortunately, it's been laid out very badly and it's a real PITA to work on, components are nearly impossible to repair.
TiefBass, you seem to have a very nice collection, it would be nice to meet you ...

The showed device collection isn't from me.
If I had this collection (along with those from in post #1 mentioned thread's), I would have one of the world's largest collections.
Unfortunately, the devices are not shown my own collection, but from my virtual photo collection, which I has stored over the years in my computer disc.
If the overview is big enough, I can make better a decision, which components I would like to have.

What means "EV-like" maybe "Electro Voice" like? what is a "real PITA"?
The "SG-999A" isn't difficult to repair, if no mechanical stuff (like tonarm) is damaged. What is exact your error description? You mention "components are nearly impossible to repair". Which component?

BTW - Thanks for the photo and schematic. There isn't to find online.

Default Solid State Integrated Amplifier from Cabasse - who knows the Model?

This solid state integrated amplifier from Cabasse I have also found by chance. It is equipped with germanium power devices. Perhaps it was the first solid state amp from this brand. Schematic and model No wanted.
Very special for that time is the dual monaural Baxandall equalizer unit so as the icon for the balance regulator. This amp haven't to do with that one from last (third) advertisement photo.
