Hello all,
Yet again I was trawling the bay for no particular reason (a dangerous thing to do) and happened upon this AM/FM signal generator. I recognised it immediately as I used one for many years at my previous employment. It was the reference for many a tuner that was produced and returned for service !
Anyway, this one will be winging it's way to me shortly and will be a very useful item. I obtained it for £90 so think it was pretty reasonable. Here are the vendors photo's of the actual generator for now.....
Very nice bit of kit, and a great price !
It appears to have a Stereo Encoder built in, is that correct? Is it wideband FM or will it do narrow as well? There are "begin and end " decade switches ,will it perform as a sweep gen?
Sorry lots of questions. Nice piece of test gear.
Very nice bit of kit Andrew, your certainly building up a nice collection of test gear now

Hi Frank, yes it has a stereo encoder, and as far as I remember, it is wide FM. The decade switches are to select a range of pre-programmed signal conditions that can be stored in memory and can be retrieved quickly by rotating the dec-inc dial and pressing recall. If working, this is a useful feature and avoids lots of fiddling about when several differing signals are required.
I will try and obtain a manual for this as I learned how to use it at work by purely trial and error lol

Thanks Marc, it was a pure chance that I happened across this item, I can't even remember exactly where I was browsing on ebay.

Let's hope it is fully operational..... watch this space 
Again, it looks very useful with the added bonus of a stereo encoder. I acquired a Heathkit stereo generator from the Wireless Museum for a couple of quid which is going to need a little work to restore functionality; currently I have an Armstrong tuner-amplifier which will not decode stereo despite working through some bodges and blinders on the decoder introduced by 'enemy action'. I noticed that the cores in the detector transformer had been 'got at' and I wonder if the alignment has been compromised enough to lose the 19kHz pilot tone; the decoder in the Armstrong is directly driven by doubling the 19kHz tone to get 38kHz to drive the switching elements - a pair of AF11whatevers.
Hi, well I am now in possession of the user and service manual for the LSG-216. (Plus 330PDF files of other Leader equipment).
I obtained them via an electronic download from this company.....
www ultimateservicemanuals com
There is a MASSIVE range of manuals that maybe purchased from them and their site is well worth a browse.
(For instance, the Philips vintage audio, radio and TV DVD (or download) contains a whopping 2340 service manuals alone. All for about £16.00).
Hi,
Today it arrived and does appear to operate as it should, you never can be quite sure, so am very pleased.
(470khz carrier, then AM followed by FM)
@pye625:
I'm currently servicing my old faithful LSG-216 as it has developed several age related problems as:
- memory loss (NiCd memory battery)
- quirky attenuator (4 relays inside VCO module)
I solved all these problems but I'm still trying to locate the main reference crystal oscillator (with a trimmer capacitor) as the generated frequency is off by about 55kHz on the 75-115MHz band. Some help from someone who owns the service manual would be greatly appreciated.
Mod Note:
Putting a : at the end of the mention for pye625, invalidated the syntax of the mention therefore it failed to notify him. The post has been edited and a new syntax correct mention added. The old was left in place with a strike-through, by way of example where you went wrong. A correct mention will end up being a link ( blue) that points to the members homepage.
Hope this advice helps you.
Get in touch with Leader directly - they're very good on service manuals.

That it is, and sort of kicks my humble function generator into the trashcan! - Just when I thought I was finally going places too! 💥🙀🤦
