Heathkit AR-2000
« on: November 25, 2022, 01:56:25 pm »
The Heathkit AR-2000 was a medium-high quality domestic tuner-amplifier, 2*20W RMS output into 8ohms, tape + mag phono + ceramic phono inputs, and an LW/AM/FM and SW tuner.

When I was young in the early 1970s and "Hi Fi" music was a hot topic, my parent's 1950s mono record deck and valve Heathkit amplifier weren't cutting the mustard any more. So my father and I assembled a Heathkit AR-2000 tuner-amplifier together as a project over the Christmas holidays. I'd stuff the boards during the day, he would check them after work, and I would solder them. ISTR buying an Antex 25W soldering iron for the job - standard decent quality at the time.

I've recently "repossessed" the AR2000, and decided to see if it would work and how good/bad my assembly skills were.

Summary:
  • the front panel LES bulbs had mostly failed. Easily replaced, thanks to fleabay
  • a 100mA fuse had blown, but since it was only carrying 25mA, I just replaced that
  • it appears to work (with a 40us risetime!), but I haven't connected it to loudspeaker
  • shame about the scuffed cabinet
  • the scale illumination is as uneven as ever, but that was normal then
  • the soldering isn't bad, and certainly nowhere near the (lack of) quality that some Heathkit gorillas perpetrated!

There are lies, damned lies, statistics - and ADC/DAC specs.

Nice looking receiver and pretty good inside as well, nice and clean and soldering looks to be perfectly OK to me.

The 18w version is still my everyday iron of choice,must be 40+ years old and still going strong.

True, but that might also be a reason why so many of the old gear is still going strong today, plenty of natural ventilation to keep things cool?
