hi all,

peter c, an old friend of murray's has
this fantastic stack of ecofan gear.

3 way system with amps for tweeter,
mids and bass. one amp has internal
crossover; one external crossover,
switching unit, line amp and phono stage.
bass amp has, i think, partridge OPT's.

speakers waiting for new woodwork but
are kef/bbc units.

cheers,

adam

Correct. The amp on the bottom is basically the Super Audion Mk-IV but with power supply separated and Peter's provided Partridge OPTs.
The "Mid" amp is one of the Super Audion Mk-III ones. Both of those amps are tranny driven, rest of cirtcuit direct coupled.
Top one is a "Tweeter Amp" I made a few of. They have internal crossover and air cored OPTs.
One of my old "Audion" preamps above the Scott tuner..

Here is my friend Julian Mitchell, owner of a Super Audion Mk-VI amp who brought in his Leak Point One pre-power combination for a preamp switch problem to be sorted. That is his beach bach system.

"Robojock"
Garrard Type A.
Side pusher rather than centre muncher.
Frequency locked synchronous motor.
Really heavy decoupled cast iron platter!
With my mods it operates at one gram.
Long ago the massive clunky original arm replaced by Pritchard rosewood arm I happened to have at the time.
Current cartridge: Garrett Bros P66 "Dynamic Coil" high output moving coil.
For a long time I used a Shure M75ED.
Everyone is highly impressed with the sound of this machine.
It'll stack a dozen, but for 12" EPs I use a "Sonic Research" acryllic hard mat for six records optimizing the VTA. About a dozen 7" 45s on the original mat. It does depend on the thickness of the records. Ten of 78s, but not with this cartridge! I have a 78 stylus for the Shure, and used to add a coin to the top for those.
I do need an extra Pritchard head shell!

A couple of wee mods I added which are not very noticeable in these photographs.
The Decca Lifter I added so that you could "pause" if the phone rang without rejecting the record.
The other one is the little stylus cleaning brush on a spring, as in a jukebox, which scrubbs the stylus between records!
The decoupling under the cast iron (which is heavier than the aluminium one on the 301) was a donut of foam. Currently I have two donuts of blister pack with a felt one in between.

When I was a young apprentice at Akrad, Ron Skinner, one of the supervisors at the time, used to take us for night classes.
In the "radiograms" they made, the turntables were horrible BSR, Collaro etc rubbish, and I wanted to get my HiFi good. I already had 5 cubic foot one and a quarter inch ply huge speakers in my mum's sitting room!
He said: Garrard have come up with this Type A. It's a side pushing changer with heavy decoupled platter etc. We're not going to use them, but I can get you one out from Garrard as a sample if you like.
Good old Garrard! They shouted me this wonderful machine! It could be the only one in the country.
Has anyone else on the site got one?
It's certainly way ahead of any old 301!

What a fantastic contraption! Congrats.

Side pusher rather than centre muncher

Sounds like a girl I used to know!
