Re: Ferrograph Series 7 Model Number Identification
Mine has the [natural] wooden lid Peter [post 20*]. It looked out of place so I thought it might have been added later. I'm surprised to hear that it's original!

Re: Ferrograph Series 7 Model Number Identification
I'd love to see a picture of it Dave. It certainly sounds like the ones I've heard about. It almost seems that Ferrograph overlooked putting a lid on the "7".

Re: Ferrograph Series 7 Model Number Identification
I still use a Clamshell phone Peter [rarely] but I will get someone to do a photo when I "Hit The North" [as Marc E Smith would have said

Re: Ferrograph Series 7 Model Number Identification
Yes, they are easy to get, I’ve made a couple of cables for testing ex-BBC equipment that comes my way.

Re: Ferrograph Series 7 Model Number Identification
Interesting that the 'complete' one has a silver head flap/cover. Most Series Seven's that I've seen have a black flap.
Also mine has an extra tape guide on the left hand side, just to the right of the small black circle (which is the reel height adjuster). This is part of the auto-stop foil detector (which detects a short between this guide and the tensioner just to the left of the heads - I assumed all S7 had these fitted? I wonder if that is another BBC specific mod - i.e. no auto-stop fitted? |

Re: Ferrograph Series 7 Model Number Identification
Black flaps and inserts in the spool turntables indicate Mk2, if memory serves, along with squared-off head cans, which wore better than the Mk1s.

Re: Ferrograph Series 7 Model Number Identification
Yes Ted you are correct, my 722/Mk2 has the black flap & spool inserts; although my machine has the round cans on the heads. I don't know if this is an early MK2 or maybe somebody did a head swop sometime in the past.
As for the foil autostop, at least the swinging arm is there so it wouldn't be impossible to re-instate the stationary pillar if required. When I was involved with student radio we used Ferro 7s as juingle machines in the early days - they could be remote started from the mixer and the foil stop was very useful! Eventually we got hold of a couple of cart machines so the 7s were used for better things thereafter. |

Re: Ferrograph Series 7 Model Number Identification
I was going to ask about the holes in the reel tables, I noticed that the incomplete unit does not have the holes.
So what are the "inserts" ? are they missing or fitted in the photo of the complete unit ? If it is a Mk. 2 (silver flap indicates Mk. 1 ?) is that generally a good thing for the Series 7 ? |

Re: Ferrograph Series 7 Model Number Identification
Are the holes in the reel tables not there just to hold the 3 rubber inserts in place? The photos look like the inserts are missing in the complete one, but are present in the incomplete one?
Mine has the inserts, and has the extra tape pillar/guide and has a black head flap (so it's a Mark 2?) - but it has round head cans! But then my model number is 723 which I can't find any record of ever having existed, so who knows what is should or shouldn't have! |

Re: Ferrograph Series 7 Model Number Identification
Hi DMc,
As far as I am aware the differences between the Mk1 and Mk2 series 7 are minor: 1. The earth return for the foil stop and tape-out stop are wired to deck on the Mk1, but wired to the removable panel carrying the flip up head cover on the Mk2. 2. There may be circuit differences, but I have been fortunate enough not to have to delve into those . . . so far! 3. The Mk 1 has a silver head flap vs the black anodised flap on the Mk2. 4. The Mk1 doesn't have the pair of fixed pillars on the RH tape-out arm assembly. I'm sure there are more differences, but hardly deal-breakers. The only function I can think of (other than being purely cosmetic) for the rubber inserts is to reduce the amount of heat coming up through the holes when the deck is horizontal, but given that the RH hub gets fairly warm anyway, I'm not even convinced by that - so maybe it was just to make it look pretty. The other issue is that if the machines come from a company environment, the technicians would probably mix and match to keep them running, so you could have a Mk2 with Mk1 heads (as I suspect I do), or a Mk1 with a Mk2 head cover etc, etc. |

Thank you Ferrograph723, Mistral13 & Ted for the Mk.1 / 2 info.

Re: Ferrograph Series 7 Model Number Identification
One thing I’ve noticed David after looking at the Ferro pictures again is that the spool retainers are not fitted. They resemble the knobs of the amplifier but are cut with a thread and they screw onto the reel table shafts. If you don’t receive them might be worthwhile asking the seller. They will be necessary for vertical operation, I’m not sure if the old locking Ferrograph spools would be a satisfactory alternative.

Re: Ferrograph Series 7 Model Number Identification
Thank you Peter, I did notice they were missing on the complete unit before I brought it, that is one of the reasons why I was also attracted to the incomplete unit, as it looks like they are fitted on that unit (I hope I am correct).

Re: Ferrograph Series 7 Model Number Identification
Both units have just been delivered (that was quick), still to be unpacked. They are certainly heavy, even the incomplete one.

Re: Ferrograph Series 7 Model Number Identification
Congrats on the new arrivals! Yep, they're heavy - my workbench is up in the loft, and I can tell you, it was a struggle getting mine up there to work on!
Don't forget my offer to buy one of the lids if it's surplus to requirements : - ) Last edited by Ferrograph723; 3rd Feb 2020 at 3:46 pm. Reason: Wrong smiley! |

Re: Ferrograph Series 7 Model Number Identification
Just a few minutes ago, got them unpacked and had a very quick look, basically as expected from the photos, not great condition but not terrible. They do have metal cases and lids, grey/blue colour maybe Battleship Grey.
As expected no mains cables, various loose fittings in the incomplete unit including one of the spool screw on clamps, I think maybe the stud that it screws onto has broken out of the reel table (will check more precisely later), the other spool clamp is screwed on in-situ. As expected no spool clamps in the complete unit. As almost predicted by Mistral13 the Pinch wheel is missing from the complete unit and the incomplete unit. As seller had said there is no serial # label on the complete unit (a shame). Have not forgotten Ferrograph723 about the lid request. I will check everything in more detail a little later and post a few photos. Both lids are intact and all 4 fasteners look OK both lids could do with a coat of paint through to smarten them up but they are not that bad. |
