We recently had a customer present this faulty Alchemist Forseti integrated amp for repair - I'd guess this dates from the 1990's and has been well looked after. It's a bit of a bruiser as you can see from the extensive heatsinking!
Alcemist Forseti integrated amplifier
Unfortunately it developed a DC fault on the loudspeaker outputs and destroyed the customers speakers, so it's now in the naughty corner awaiting surgery.
We just had to have a look inside this recently part exchanged Quad 909 power amplifier - a powerful beast, superbly constructed from the finest materials.
