Got myself this Dynatron Jewel at a reasonable price for my first newbie attempt at restoration. At first I thought it was dead but after much head scratching it suddenly sprang to life, albeit with low volume and a hint of distortion.

I'm sure the culprits are the electrolytic caps in the amp section which have odd values such as 350uF and 8uF. I guess it's OK to replace these with the nearest equivalents, 330uF and 10uF? And does voltage rating matter as long as it's more than the 18V operating voltage of the radio?

Cheers,
Tully
