Hello all,
My Dynakit ST-35 just blew a fuse...replaced it, then instantly blew again and again. I have noticed it has been running hot... It has the original filter caps. Hopefully it isn't the power transformer...but it was built in 1966...so it does have age on it.
Anyway, I pulled out my multimeter...made sure caps and power were 0V. I started simply testing connectivity at the diodes, transformer secondaries and such. I then discovered that the speaker terminals show connectivity to each other including COM and Chassis...all terminals 8ohm, 16ohm, com and chassis have tone when testing for connectivity to each other. In any order...left channel 8ohm beeps when I touch the right channel 16ohm terminal...8ohm beeps when touched to com.
It is disconnected from the speakers...in case you were wondering.
Is this normal? Am I just tripping? How and why is the left channel 8ohm terminal connected to the right channel 16ohm terminal? Aren't they exposed to be isolated from each other?
I'm hoping someone will enlighten me...and anyone else with this question.
Thanks
