Default PT options

Hello everyone,

It's been a very long time and i still couldn't finish my Tubelab SE amp Things were crazy. Anyway I have a question.

I am living in Turkey right now so I ordered James Audio PT, which works with 220v.

However, next month I am moving to Los Angeles, CA. And hopefully I can finish my amp there . I don't think my 220v James Audio PT will work there right? Is there a way to make it work there? Or should i just get a new one?

Thanks.

Can you check if your James power transformer has dual primary option - supports both 115V and 230V mains?

That is an excellent question. Unfortunately i lost the connection diagram. But i see 110v on the PT.

My PT's model is JS-9612-2 maybe someone else has the diagram and kind enough to upload it here?

I uploaded the specs

I found the wiring diagram. Which says i can get 110v. Would it work in the States?

That's why I asked to check. Some power transformers (especially more expensive models) support multiple primary voltages. Looked like you picked a winner.

It may be a little higher or lower than 120v. I've seen mine as high as 126, and it usually runs about 122.

The voltages out of the transformer will be slightly higher when 120 ish is applied to the 110 primary. It probably won't be a problem on the high voltage secondary, but it may push your filament voltage up close to 7 volts.

You'll just have to take some measurements when you get here and see where you're at. Might want to leave room on / in your chassis for a small filament transformer to buck the line voltage if it looks like the voltages out of your transformer are too high, or just use a separate filament transformer made for 120 volt primary.

Much less expensive than buying as new PT!
