Hey all,
I'm a pretty new DIYer and am working on building a Spectra Sonics 110A from scratch based on the schematic. I have the circuit breadboarded and have been testing it to get it functioning before I put it on a PCB and chassis, etc. However, the output is very distorted. I have a 600:600 transformer on the output but none on the input (I plan on acquiring the appropriate input/output transformers when I get the circuit working). As far as things within the circuit, some of the transistors and resistors heat up excessively (I've had a few resistors fail). Essentially, the main problem seems to be that the circuit is drawing way too much current. I'm not totally sure if I have all the inputs/outputs hooked up right or not.
Does anybody have any ideas or suggestions as to how to get the circuit working properly?
Thanks!
