There is a ton of used BK Precision gear on eBay...

I looked at a lot of them. Few were much less expensive than this new unit:

I would much prefer to have a digital set one than an analog dial one. The cheap one I use allows for 10mHz to 60MHz and 1mV to 20Vpp. My good Siglent goes from 1uHz to 30MHz and 1mV to 20Vpp but also allows the two channels to be tied together to generate an AM signal plus a few other tricks the cheap one won't. The devil is in the details. There are also some spurious noise issues with my cheap one that the good one does not do. Listen to Yaakov!

 

I didn't realize that what I purchased was analog. And I sure didn't mean to not be following Yaakov's advice!
I will return my order and try again. This is something I should have watched earlier:

But this is apparently not correct in the case of that B&K:


Most current function generators adopt a digital approach to the waveform generation. Some older function generators may use analogue techniques, but it is unlikely that any new ones will.

Another Wavetec 3FG at a higher price:

Suggestion. Make a list of what you really need, frequency, waveform, voltage, functions, etc. Then when you find something get its operations manual and see if it meets your requirements. The ad title throws out 10MHz, 100MHz, but it is in fact a 2MHz waveform generator. If you are interested in a 2MHz sig gen it is a good one. My only concern would be all the knobs. Are they pots (analog) or digital selectors (digital)? My sig gens have 1 large digital selector knob and lots of buttons. You can set freq. and volt. by knob OR enter it exactly by keypad. Once again, the devil is in the details.

Thanks for sharing your knowledge SamR. AFAIK, most any unit will produce what I need.
I hope to be able to recap, repair & tune vintage audio. (for fun not profit)

After seeing what they want for old equipment, I am thinking of buying new.
(also considering 20+ year capacitors in the the used equipment.)

 

There seems to be 2 different schools of thought on electrolytic capacitors in old equipment. If they don't leak and aren't bulged, leave them alone vs. change em all. And, 2 MHz definitely covers the audio spectrum but I'm no audio equipment repair expert!
