Toshiba 330 power amp

Cool 😎

I've a vague recollection of installing one of these back in the day for a customer. We were sometimes called on to help out with installs when things were busy... pretty sure I remember doing one of these.

Way better (different league altogether) than the Amstrads and Binatone 'pretend' separates that were so popular back then. Or Grumpstrads and Whingetone as I called them 😀
 
So without any bias current and then with a few tens of milliamps.

And with the three diodes shorted as we originally had, and where you felt you could hear the distortion.

The real world figures will vary quite a bit but you get the idea.
