at the moment listening to:



McIntosh MR71 tube tuner from 1965

I had one of those. Beautiful tuner - the best one I ever owned. The sound was sweet and natural. It might not have been the very best DXer but I think it was the best sounding McIntosh ever.

That amp under my name is a modified Stereo 70 from around 1960. Those are the original output transformers. The power transformer is off the chassis, hooked up with a fat umbilical. It was modified by American Hybrid Technology around 1989. Dan Fanny designed all the boards and solid state rectifier - a lot more than just a diode. Those are EL34 with 6FQ7 input tubes. It puts out 50wpc and has a rise time of 3 Usec. It was originally my tweeter amp in a biamp set-up.

  Hmmm, wonder what the frequency response of that power supply is, with those *gigantic* caps.  I know that's the way they did it at the time, but wow.

I've never seen another amp with this kind of storage, at least one like this. Those big caps are 5400MFD @ 200V, strung in series to make 600V. I found them back then in an ad. I think it was in Audio mag. Those other caps on top are bypass - speaker caps and resistors to make it discharge faster. I don't know about Freq resp of power supply, but the amp passes a perfect square wave at 1K and 10K (near perfect). So response to 100K or close. It was designed as a tweeter amp. The high end is flawless. I use it full range now. It has slam bass and a totally effortless detailed sound. Two techs fixed it recently, replacing some old resistors etc. Both of them remarked how nice it sounds. One of them builds tube electronics.

Danny was a tube god. He used to modify ARC and stuff like that. My other amps at the time were direct drive electrostatic tube amps. They drove Acoustat panels at 50KV. They had high voltage TV cap tubes. They also had storage - banks of photo flash caps and custom made 25KV suckers. They were lots of fun.

Most of my audio gear is about 20 years old. My wife and I both bought 2 channel systems at about the same time. I have the following:

Yamaha AX-630 integrated amp
Denon 5 disc CD changer
Baby Advent II speakers
Boston Acoustics HD9 speakers
Boston 525v center channel

There is also a Denon 2 channel receiver of the same vintage that I am currently not using.

I have Luxman PD-284 and PD-277 turntables, they are from the late 70's and a few Luxman Preamps, including the C-350. It is also from the same time period.

Since the C28 Mac preamp went south, the oldest piece is my 70's McIntosh MR78 FM Tuner.

We have some local stations with good Jazz and Blues programs.

And there is always Car Talk with the tappet brothers and Prairie Home Companion.

Take care,

Philips LHH1000 CD-tranport and DAC -1989

Traded most of my LPs as well as my turn table for it. Four dedicated power supplies for transport, digital circuits and L-R analogue channels.  Replaced several rubber belts in the transport mechanism over the years but i'm confident it'll be fine for the next 20yrs.  :green:
