@crustytv I have successfully made a copy of the G11 tape, it was a bit of a test of my patience, as Mike said the squeak was transferred to the recording, and despite my best efforts side one was muffled.

How I got around it was to transfer just the tape to a new cassette.  I put two bare cassette decks on the bench so I could access the spool spindles. Then I took the tape off the spool on the faulty cassette pulled it out through the slot fed it onto the spool of the replacement cassette and wound the tape out of the faulty cassette into the replacement. This took a while as I had to do it slowly so as not to tangle the tape.

Once done it played very well, not muffled and no more squeaks! I then made a copy of the cassette which is pretty good. The 'original' tape is a copy so it isn't hi fi by any means.  The other half had to go to the post office this morning so a copy is on it's way to Chris. I have sent it recorded delivery so hopefully it should be with you tomorrow Chris. 

I hope to do another copy so Mick can have his original tape back with a backup but my cassette deck has now thrown in the towel and has no take up. A job for another day!

No worries Chris. Honestly, you providing this forum is much more than adequate payment! I am pleased to be able to contribute. I really enjoy my time on here and often read the repair blogs.  I hope to be able to contribute  some articles in the not too distant future, I really need to get some bench time. At the moment like a lot of us I am looking at trimming the collection down a bit and at the moment for various reasons time in the workshop is a bit limited... I hope you like the tape, the few parts I have listened to so far do sound interesting.

Thanks, Rich, please also pass on my thanks to Mick for sharing his tape, glad he had the foresight to save it, many would probably have binned it long ago. It's wonderful to capture all this old trade material, such as the videotapes, I discuss in the 1st post of this thread, I had no idea there might be audio cassettes about.

I'll set about capturing this G11 tape, then hopefully either upload it to the main website, under the G11 Project page, or if it's too large to host the file on the VRAT server, I'll host the video on our VRAT YT channel and link to it from the G11 page.

Hi Rich,

The tape arrived safely at lunchtime today. 👍 

Here's a little teaser for those interested, I shall digitise it properly and upload it in due course, most likely accompanied by the G11 project brochure images to the sound.

I've not looked through the G11 Project brochure for quite some time, on page 38 it mentions the "Teletutor" cassette. I wonder if this is the tape?

It certainly looks as if it is. The tape does refer to the publication. Would Philips have produced more than one training cassette, Maybe, knowing Philips! It is a wonder that power supply protection wasn't provided by a Bowden cable! I guess the neon lamp starter thing was cheaper??   I wish I had knew of the tape's existence back in the day as the one day lecture was a lot to take in as a 16 year old apprentice.  I liked the G11 and still do, as a certain Mr Daily would say "a nice little earner" !

Upon receipt, yesterday evening, I digitised side A of the G11 Teletutor cassette via Audacity. The tape originally would have been accompanied by the course booklet, which is frequently referenced by the narrator. Upon searching my service data, I was amazed to find I had it!!  Using my Video production software, I imported the audio, then extracted and then imported all the visuals to cue, thus now making a fully featured training experience for the Philips G11 owner. As I say, this is part one, covering the G11 power supply, part Two will follow in due course.

I hope those of you who are ex trade folk will enjoy reminiscing, perhaps even refreshing yourself on the PSU, and those of you were not trade but have a G11 in your collection, will enjoy fully understanding exactly how the PSU functions.

Finally, a big thanks to Mick @mickmcmichael for having the foresight to keep hold of the tape for almost 50-years and Rich @slidertogrid for saving it via shell transplant then sending a copy to me.

It's 40 mins in length, so grab a coffee and Enjoy!

So far I have watched about half of the tape and only got one question slightly wrong. My brain isn't as fried as I thought! 😆 

@crustytv I am really impressed with your video of the tape - very professional ! We could have done with something like that in 1977 !

Part two covering signals processing, timebases and the 20AX system.

Note some pages for illustration were missing from my booklet at the very end.
