Voltage conversion of Accuphase E-5000

@foolishman 

Sorry, I have no experience with voltage conversion with the Accuphase C-47 and PS-1250 either.

I'd love to know how to do that though! If you could provide some close-up pictures of both sides of the power supply board in your threads, maybe we can figure it out.

Thank you very much for your response.

I will try to take some pictures for the power supply board of those items and post them.

Thank you again.

@imhififan

Again, meanwhile, do you know how to convert voltage of the Accuphase C-3900 Pre-Amplifier from 100V to 230V?

Also, do you know how to convert voltage of the Accuphase A-300 Power Amplifier from 100V to 230V?

I will appreciate very much if you would provide information on them.

Regarding PS-1250, do you think it is possible to convert voltage to 120V without replacing the main transformer?

Converting Accuphase amps from 100v to 120v is not straightforward as the above discussion illustrates. You can never be sure that it was done correctly or to Accuphase standards ("you can use a 680Ω 3W resistor to replace fuse F1"). The above discussion does not inspire confidence, and these units could be a fire hazard.

Given the range of units that have been mentioned above for conversion (E-5000, E-700, E-4000, DP-450, C-47, PS-1250, C-3900, A-300 - and C-2300 in a previous thread) this sounds more like a business venture as opposed to someone putting together a personal system. These units could appear on the secondary market. There may be some attempts at stencilling on the rear panel to hide the conversion and make them look like authentic 120v units.

I would urge all Audiogon members to be very wary of buying units that have been converted and relabeled and to carefully investigate the provenance of used units.

Caveat emptor!
