OT: Hi-Fi audio amplifier kit

[Johnny Siu]

Hello Group,
 
We all enjoy our kit building experience from Elecraft.  Are there any kit manufacturers of Hi-Fi audio amplifier (or related audio products) in US?  Of course, I am looking for high quality equivalent to Elecraft.
 
I am just dreaming an audio amplifier kit from Mark Levinson or Krell.

TNX & 73,


Johnny VR2XMC

Back around 1955 or so, I built an Altec-Lansing audio amplifier from a kit.  Although that company had a pretty good reputation at the time, this device wasn't anything to boast about.  It used eyelets to interconnect both sides of the PC boards and many of them had poor conductivity (that technology should never have seen the light of day--I have also seen Motorola and Icom products which also suffered from intermittent eyelets).

Yes.  That WOULD be interesting.  Not since Dynaco in the 70's have I
seen a decent Hi-Fi amplifier in kit form.

Hi,

All I know about these kits is that I was reading about them recently,
they were favorably reviewed, and I saved the company link.  With that
disclaimer, the InterStage Mono Block amplifier kit will only run you
$3800:

They have a few other kits, too.

Thanks, Byron.  I should say I am looking for solid state power amplifier kit.

Plenty of dynaco amps on eBay with complete rebuild kits from Curcuo Audio , audio by Van Alstine , and a few others these two are the best though

  I home-brewed a (tube) stereo amplifier from a Dynaco circuit
  using their transformers in the early 1960s.  It was first
  class, but not up to the physical standards of Elecraft!  It
  saw over 10 years of service in the US and overseas until I
  replaced it with a solid-state integrated tuner-amplifier.

I have built the Pluto "semi-kit" from Linkwitzlab and recommend it. It is an active loudspeakers with an unconventional soundstage and design, look at http://www.linkwitzlab.com/.

Be aware that class-D (digital) audio amplifiers like this, in combination with long loudspeaker wires, don't always go so well with amateur radio. Sometimes they radiate well into the lower short-wave range. Unless of course, you turn off the stereo whenever you turn on the radio ...

A low-pass filter on the output works well, and is easy to construct if the
power is reasonable! A 3-pole Chebyshev filter works well.

In the datasheets for these amplifiers there's usually a recommendation to
do as much unless the cable to the speaker is very short (ie. built into the
unit).
