I can certainly let you have the schematics for the 828, but I only have details of the series 2 version…. but that’s likely to be the one you have.
As for pots, these were ‘Omeg’ pots and I don’t use them or hold any stocks any more, but you might find them in RS or Farnell.
I will email you the circuits and layouts.
I’m from Hungary and speak very little English. Sorry.
I have a Alice 828 (MHF 24-1-83, SN: 777-2357), but unfortunately it does not work. Maybe any IC (HAI-4741-5) broke. An alternative would like to ask us for this IC is unknown. As can be replaced?
It would be nice to have a schematic, to see the connections as.
Hi Thomas, the IC you talk about is the Harris 4741 and it is probably difficult to source now. It is simply a quad version of the 741 and has the same connections as the TL074, and you could probably replace it directly with the TL074.
I will email separately with the circuit diagrams.
