So, I bought a Dynakit ST70 and have a couple questions. I hope they aren't too obvious, as i am just a beginner and will probably ask some dumb questions.
Here's the front of the amp. I have a couple questions here:
- In the far left corner there is a toggle switch. What function does this perform? I couldn't find any similar pictures. Is this for triode/pentode mode?
- It looks like I have 2 quad caps. Is this common? The tube between them seems to be like a relay.
Here's the label on one of the cans. it's made by Sprague.
Here's a peek underneath. Looks like two chokes. Is this unusual?
Here's a couple closer details. I am wondering whether the dreaded selenium rectifier has been replaced.
Here is the power transformer. I know that the original PT could get rather hot. Is this transformer up to the task of driving KT88, or should it be upgraded?
Lastly, the OPT.
Thanks for any tips you guys can give me. I'm really excited to start using this amp!
