The power light on my very old ARCAM Alpha 10 amp doesn't come on -- nothing works, it's like dead. I have 120 volts on the power cord.
Any suggestions??
Thanks.

Diodes age/time out ? Did on My Arcams. mebe yours too?
That said, the Sound quality the contraptions generate, when healthy,
makes bothering to repair it fairly Dubious IMO.

Check mains fuse, if blown that's probably so for a reason. Usually degraded power supply capacitors that fail to sustain full voltage (the big ones), dead rectifier diode(s) (possibly as a result of the former, usually shorted then), or bad power amp of course. Haven't looked at the schematic of this unit but being able to disconnect the power amp section from power tends to help in fault-finding.

This is quite a complicated and hard to follow design with soft-start and microprocessor control over all operations, including the start-up error check sequence and conventional protection devices. If you read the other threads here on this model, you'll find that inexperienced DIY repairs (other than rare simple fuse issues) are going to be impractical and unlikely successful unless it really is just a trivial fault, as mentioned.
Arcam will recommend return of the amplifier to them for a full refurb/upgrade which is a pretty good indication of the likely problems inside and the potential cost of repairs by service agents or others. I'm sure this will be uneconomic but I would seek professional help all the same. Check the main fuses by all means but fault finding and repairs are not going to be simple or cheap.

Thank you Ian for your suggestions; sounds like I need to replace my Alpha 10 Integrated amplifier.
By chance do you know how I might proceed in replacing a fuse? I couldn't find anything on the rear of the amp that allows fuse replacement, so I presume I should remove the case and look inside.
Thank you.

Need take the case top off Inside near the transformer you will find the Fuse(s) one for 115 v the other for 230v.
Only one will be fitted replace with A Slo blow type
Might work, most likely not... fuses usually blow for reason.. (Failed diodes 🙂
Again.. in MY experiences these Arcams are actually ..Poor.. sounding Amps.
Despite Brochure Bbabbles and usurious pricings
Simply Not worth owning, let alone fixing.
