Heathkit audio generator model AG-9A test teardown

this unit is from about 1960 was sold as a really cheap kit, the one i got here was modified to save the heat loss from the tube rectifier, needed a lot of contact cleaning, then we got nice stable output again, worked from 5Hz to 100KHz. See also this video only 5 mins, but it is very good to explain the AG-9A have a look too:    • The Heathkit AG-9A Audio Generator   #heatkit #teardown #repair -- I use auto generated subs, so if you find errors worth fixing, please comment with the time in the video you saw the error, i will be happy to fix it.
