Hello DIY Audio'ers. I own a Theta Data Basic I/II (upgraded apparently) which runs on 110v with a step transformer to 230v for UK use. I recently had a senior moment and plugged in straight from the mains :eek: Instead of blowing the fuse, one of the tantulum capacitors blew from the over voltage.

Unfortunately I cannot find a schematic or advice anywhere so I was hoping that some kind soul, who also has one, would have a look on their circuit board at C17 and be able to let me know what value they have.

Fingers Crossed
Thanks

The capacitor for C17 is marked "+100" above "16". This is from an US Theta Basic II. The C17/C18 positions on my board are different from your picture. Also I replaced all the electrolytic capacitors and the bridge rectifier after 20 years. Big difference is SQ!
