F307 is one amp I'd LOVE to own for some strange reason....

They need a few circuit alterations but your clearly a man of great taste Dave. The haters/piss taker are generally from cloud cuckoo land, they generaly own artifical sounding systems anyway so never appreciate a good item...

HiFi Dave isn't one of those people I can assure you.

KJ did Ferrograph in the early 70's, but by the time I started as a saturday boy in 1974 the interest had waned. By the late 70's, the W1 shop re-stocked Ferrograph with the Super7 to start with and the 307 amp, together with a batch of twenty pairs of "S2" speakers that noone except me have heard of.... They looked identical to the S1 but were supposed to have re-jigged crossovers - I loved them and would have bought a pair myself except I bought a colleague's BC1's instead (in 1976).

The F307 wasn't hugely powerful and it was obviously laid out internally in the old fashioned transistor way on olde-worldy circuit boards, but the front panel looked quite professional to me and the controls felt nice as I recall. I think the sound was ok too.

The last I remember of ferrograph was the rather tasty Logic 7 reel to reel. I recorded some stuff for dem and loved using it, the Revox B77 being a bit plain-jane by comparison.

One of my colleagues made a demo betamax tape with a camera "walking" around the shop. I wish I had it as the pics of the equipment we had then would bring back so many memories..

Andre, you're driving me bonkers with that F307 avatar. I have no need for it now but the F307 is one amp I'd LOVE to own for some strange reason....

"The F307 received a number of good reviews and sold in relatively good numbers.

The electronic design of the amplifier did have shortcomings which could have been tackled at the design stage, with no stabilisation of the power supplies. Loud passages or a heavy bass line would cause the 'power on' lamp to flicker in sympathy. The amplifier went into a "Mark II" version with an improved specification and to also address shortcomings in the power output stage. A military version was also supplied (and housed) in the traditional battleship grey livery and sturdy metal cabinet."

Quoted from 'Built like a Battleship - A History of the Ferrograph Company', by Terry Martini, 2008, ISBN 978-1-4276-2523-6.

I just love the idea of a military version!

This is the perfect amp for my nuclear fallout shelter...

Give it a rest dudes i'm well aware of this amps circuit & what needs addressing.

Nice one Andre! Thanks!

It's actually being shipped straight from the seller to Mark at Audiocom for a selection of mods.

Awesome deck, very thick alloy floating top plate..Deck construction is bonded MDF, the floating suspension is three point adjustable (From top with allen key) threaded points that each sit in a sprung like cradles..Platter, Sub platter/ bearing have gotta be one of the best, substantial & well finished of that time.

Providing when you bought the deck some feet were a grey adjustable marble type effect plastic tapred foot some aluminium..Later models are best with the big coils spring in the centre over the main bearing housing.this sorted moaning reviewers that would find anything to make it look inferior to that other deck.

btw: that may be a felt matt he has sat ontop of the original as these should have an integral matt with aluminium set in centre to accomodate record label.

I think i still have those locking rings he has missing on that auction.Thats a manual version btw, there was an electronic version with touch button control pannel glued to the top as used on their 'Tempo' deck, i think the twin motor Logic 'Gemini' deck had the same pannel aswell.Only drawback apart from the slightly rough plinth constructon (inside) is the poor quality lid.Doubt you still be able to source a living 'DM101' outboard power supply but i guess the Manticore systems PSU will be the closest thing! 'Airpax' Motor is mounted on a very substantial black metal plate, fixed flush, directly into the top of the plinth.

Mooching on eBay found a pair of quad esl63 speakers recently serviced for £900 bin...

The last ones sold for nearly £1500
I know nothing about these things or thier value but thought it might be worth pointing those facts out to people, in case it is as interesting as my untrained eyes and mind would say

[Rare Bird]

Hamish the 63's need more space than the 57's as they readiate sound in different ways.. 63's also had obvious technical improvements over the '57 but i still prefer the 57's! These designs can be very daunting to someone new & you just can't plonk any old amp on em either.

[DSJR]

63's need to be off the floor and the domestic versions should be tilted back a little too. Do this properly and they're magic, although they're not right for classical monitoring I understand from comments posted elsewhere, as apparently Polygram found the old B&W 801 closer to what was actually going on in the session.....
