Can someone please recommend a signal gen for audio work?
I want to get into solid state and tube/valve amp repair.
Feel free to suggest a brands/models etc.

What other gear is handy to have?
I have a scope and a DC PSU.

Any good resources on the web? Books etc I should be reading?

Thanks

For general work I think any decent sine-square generator in good working
order would do.
Use sine waves for a general troubleshooting signal source, use square
waves, usually around 1 kHz as a good overall (quick) check for linearity.
One thing I've noticed for example, a square wave signal viewed on a 'scope
will quickly tell you if a loudness or filter switch is malfunctioning. One
channel may remain boosted or attenuated when the control is back in the
"neutral" position.
Also, square waves seem to show more easily the effects of dirty controls,
relays, etc as you are manipulating or tapping on them (when viewed on a
'scope of course).
I use a Leader solid state model at work (don't remember the model) but for
many years used an Eico 377 tube model. They can be found all over eBay for
under 50.00.
A new solid state model will run 179.00 and up.

I think most distortion analyzers sine wave generators built in - my Sound
Technology 1700B does. They can be had used for maybe around 400.00 or so.
