Jolida amp repair in and around San Francisco

Hello Folks

I recently purchased a Jolida JD-202 second hand from a friend. The amp sounded fantastic for about a week - but then around yesterday, it started making some "popping" noises. The popping more or less stopped today but the amp sounds like it has lost a LOT of it's bass. It sounds a fair bit "thinner" and flatter (the drums all sound like leather gloves being slapped against a woodblock rather than a wood stick being hit on taut leather) and appears to have lost a lot of it's audio power too (I need to turn the volume up higher to get the same sound through the loudspeakers).

I was thinking of taking it to a repair center to see if any of the tubes needed fixing- but I wasn't sure I knew any good tube amp repair folks in the city. I like in the Mission District in the city and was wondering if anyone had any recommendations they could make.

Thanks so much!

I would recommend giving Jolida a call and ask for their opinion first.
Meanwhile, You could also ask your fiend how long he had owned the amp and if he ever replaced the tubes.
Check the manual and see if the amp has any kind of fuse protection. It might be a simple fix you can do yourself.
Search your area to see if anyone can test your tubes to verify all tubes are good.
