The outside of the cylinder didn't look to be concentric with its axis, so the surface was bobbing up and down as it rotated. It didn't sound at all healthy.

Would that be due to a warped cylinder or a problem with the player? If it’s the player then maybe the Gilbert and Sullivan cylinder was chosen as it didn’t sound as bad as some others with more sustained notes might?

Looking at it again, most of the unevenness appeared to be in the cylinder, though there did seem to be a very slight wobble in the spindle as well. Hopefully, it would sound a lot better with an unwarped cylinder.

Even if that was the only cylinder supplied with the player, I'm rather surprised the repairer couldn't find a better one to demonstrate, given that he is an expert on the subject!

Exactly. I have an Edison "Standard" model that is a much inferior product (purchased from forum member OldBoffin). Even with my lack of experience restoring these things it makes a much better sound than the one featured.

When Tim Weeks opened the phonograph to look at the motor he noted that it had two springs?

There was no mention of the springs being cleaned or re-greased - this is usually essential in anything mechanical of this age.

Thankfully we have our own Forum expert Audio1950 (Barry) to advise on such matters.

I’ve only just watched that episode. All the mechanical phonographs I’ve ever heard exhibit flutter, but that example was really bad. As you say, probably a combination of slight eccentricity in both mandrel and cylinder, but it was pretty painful to hear and I’m sure Edison would not have sold any at all if they sounded that bad when new.

Default Latest BBC Repair shop and the GEC 4758

Watched this episode this afternoon but I kept getting strange feelings about this so called renovation. Did he not even check 'that' capacitor?

Yes, I noted that this week's episodes have been repeats.

Very sorry about that, thought these were all new episodes :-(
Auntie must be getting low on new material hence the re-runs (again) of Mrs Brown.

Re.post 233, the portable (fold-uppable!) gramophone that was restored in a recently screened episode exhibited a similar amount of flutter. I don't believe it would have performed like this in it's heyday- and if so there's no good excuse for a warbly reproduction. It's not rocket science after all.

Two things bothered me about the "restoration" of the radiogram.

1. The dial pointer was repeatedly referred to as the cursor, since when has this term been used?

2. After de-gunging the record player motor - the "expert" said it was time to put some current across it - surely he either meant put some voltage across it or put some current through it? I'd have thought that an expert would know the difference.

Or am I being overly pedantic? On the whole the series is better than the usual tat and worth watching. Some of the restorers have great skills.

At least since when I first started in the trade many moons ago, I couldn't see a dial, just the tuning scale.

The term cursor is used on the trader sheets, 1161 Bush DAC90A from 1954 as an example, although when it first appeared I don't know, there's a challange to find the earliest reference

I absolutely agree. I’ve watched every episode of all four series so far, and the programme continues to improve.

Time to close this thread before it too becomes a series of repeats.

Default The Repair Shop extended episodes now on BBC2

Fans of this show may be unaware (as was I) that BBC2 are now showing extended episodes from Series 4, containing some new material. Each programme is an hour long and features four restorations, with a previously-unseen one being edited in. Today's was Episode 1 (with the GEC transistor portable) but the additional restoration was actually very interesting and well worth seeing.

At the moment all I can see are six hour-long episodes in the Radio Times, scheduled for this Tuesday, Wednesday and Thursday and the same days next week. Worth recording and skipping through. I doubt there'll be any radios, but we can but hope...

That would explain why I recognised three of the restorations but not the fourth.

I missed the first bit of the GEC BT505 repair, and was rather vexed by the way the tuning knob had been remanufactured, but made way too big. If they had the skill to do it, you'd think they'd make the effort to google for an image!

And toothbrush handles for switches?
