This was a mad coincidence. Girlfriend came back from her mum's this afternoon with these.

She found them amongst a load of paperwork when sorting stuff out in her loft! Nice to have.

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

Hooked it back up to the pre amp and speakers this morning. Sounding beautiful! Bass is back, everything sounds just as it should. Definitely the best I've had it sounding. Perhaps not surprising really given how much of it is new

Really pleased

Excellent, I'm really pleased to hear that... and you can always keep it like this without fitting the presets you know

Might as well for them? Ordered them now. How much improvement will setting the bias make?

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.
