In Reply to: RE: Power transformer for NAD C162 posted by JonM on July 01, 2017 at 14:53:52
I did email the transformer manufacturer (Noratel). We'll see what they say...
I doubt Noratel will tell you anything, let alone sell you one. Your best bet is to contact Lenbrook Industries, the distributor and owner of the NAD brand.
Or contact a NAD service center and ask if they can get one.
There's one not far from here. Worth a shot. Thanks!
Heck, worst case is they ask to install it and you have to pay. But at least you have a $1000 preamp.
So worth fixing, then? Seriously, I had a NAD 1020 many years ago that I thought sounded fine, but NAD has always in my mind been "nice design, but built to a price point". (My 1020 had a factory original crack in the circuit board repaired by a factory original jumper wire soldered to the traces. I was not impressed.)
I wasn't in the market for a preamp (I have an old McIntosh that works fine). If the NAD is worth fixing, I'd gift it to my brother whose new U-turn Orbit turntable is in need of a decent preamp.
So I'll see what I hear back from the transformer manufacturer, the NAD distributor, and the local repair shop, and go from there.
Thanks for everyone's recommendations - much appreciated.
Thanks - I'll try that.
The power supply schematic is in the attached link to HiFi Engine's fine website. The supply is quite complex providing +/- 52VDC, +/- 26VDC, 12VDC, and 5.5VDC- all regulated. It doesn't seem to note the transformer voltages of the secondary windings anywhere. Anyhoo- you're not gonna find that baby down at the Dollar Tree. I'm guessing your only hope is to find an exact replacement- wait for a "parts only" unit to show up on eBay perhaps.
Thanks for that - I have the service manual, and saw the range of output voltages. There are ten wires on the secondaries - two connectors with 5 wires each that connect to the main circuit board. Not your typical design.
