Amplifier in Tivoli Audio products?

[jaste]

Does anybody know what kind of amplifier hides inside the Tivoli Audio products?

I'm posting it here since a chipamp is my guess, but which?

They can run from a battery supply so my guess would be a small class-T amp.

AFAIK it is the LM1875, but I do not find the issue of the german/dutch mag ELEKTOR, which had I opened the device to study it. But the Tivoli also uses a series of opamps to tailor the sound.
I found it too bassy, more "boomy" actually and very place-dependent - more or less unlistenable on a longer base. I gave mine to my brother as a present - and he loves it and uses it everyday.

Tivoli 'Model One" uses half of a TDA7266 7+7W dual bridge.

"Model Three"(clock radio) uses the same chip with the other half connected as an amp for the optional second speaker/clock.

I would assume "Model Two" uses the same but I have not got a look inside that model.

Tivoli spares

Hi,

Where can I find Henry Kloss Tivoli spare parts, I need the volume pot for a Model one.
I assume there is no spares, they only sell modules, so you can't repair the Tivoli products like we use to do.

So it may be a lot of DIY'ers who can make money, repairing them in the old fashion way.

I have once ordered a spare vol pot to the model one from the Finnish autohorized repair center.
I lost their contact details and their new page says they will not sell spares or give instructions.

My friends Model one has failed again and I'll give it a try and tell you how I succeeded.

Spare parts could be bought from the authorized service center in Finland, but 2.5" driver and tuning cap were each about 40euros + shipping.
I bought the driver of ebay and skipped replacing the tuning cap (quite much work desoldering it anyway)
