Tivoli Model One Power Transformer Replacement
I have an early Tivoli Model One which recently needed a replacement power transformer.
After a recent storm, nearby lightning strike and downed power lines I found the Model One's primary winding open.
I love this radio.
Turns out the Triad F-114X is a near-exact electrical and mechanical replacement for early-2000s 120V US models.
The Tivoli has no line fuse with the primary connected directly to line.
I added a 1A 5x20 mm leaded glass fuse in series with the replacement.
The Triad F-114X is rated 12V 700 mA (9.4 VA) while the Tivoli is 11.5V 800 mA (9.2 VA).
The difference in voltage and current is insignificant in this application.
This is where we talk about testing, measuring and repairing things. Sometimes we have to repair the equipment we use to test, measure and repair other things. It's an endless cycle of fixing the broken things we need to fix other broken things.
