Tour de France
I recently found a HAMEG HM 203-6 on a scrap yard, which surprisingly still works perfectly. After a short honeymoon, I have to say that it takes my little "workshop" to a whole new level. I'm glad to have an analog scope again.
As a signal source for the oscilloscope I have my PC, mobile phone and a horrible China 5$ function generator. None of these are really any fun, so I've been looking around for something more suitable.
HAMEG has produced some interesting devices in this area, but unfortunately they are still quite expensive, large and offer a lot of functions that I probably wouldn't need anyway.
So I looked around on ebay, at first I wanted to buy a tube audio generator because the optical design was soooo nice.
Unfortunately I was outbid.
Then I blindly bid on a more modern device and actually won - a Heathkit IG-18 Sine - Square Audio Generator for just around 16€ plus 5€ shipping sounded like a good deal.

Yesterday the device arrived, quite dirty, one adhesive foot missing, some battle scars but otherwise in good condition.
The device has been used and also slightly modified - a predecessor has built in a switchable 2W amplifier to (probably) drive speakers directly. Nice.
Further tests showed that everything was in order, this generator plays perfectly, all values are correct, it's really fun!
Here is one (of the numerous) videos on youtube which explains the device in great detail.
To summarize, I have to say, a top purchase, the IG-18 fits perfectly into my cheapskate setup, that's exactly what I need at the moment.
It's a great source for test signals for checking amp circuits, microphones and quickly measuring transformers.
I like the handling very much, the thing pumps out up to 30V peak-peak as a sine wave. The signal quality is very high for my purposes. I might integrate some more mods, the WWW is full of them.
The first thing I ordered was a Banana-BNC adapter. I might add a 200R position to the internal, switchable 600R termination, we'll see if that makes sense.
I am happy
