Resurrecting an old topic here but I have just started trying to build a function generator with an XR2206 and found what looks to be a very old schematic online, gave it a go and have run into some trouble so would appreciate a little advice please (schematic attached)
Seems to work quite well with a slight problem, Q1, 2 and 3 are getting VERY hot with Q1 being the worst, so much so that I think even using a clip-on heatsink wouldnt work. I am powering it from a +/- 12V supply.
I've tried increasing the value of R11, 12 to 100R and this stops Q1 overheating however this has now moved the problem making Q2 and 3 worse.
Can anyone offer any suggestions as to what I could try?
Thanks
