Pre Amp requires Service

[33 RPM]

Recently moved from Aust To Thailand , just south of Hua Hin

all my hi fi equipment safely made it, except a Harman Kardon "Citation " Pre Amplifier

works on headphones but wont send anything to the Power Amp

it may well be the electrolytic capacitors

HELP PLEASE.

is there any hi fi service centre, Bangkok is my guess, that would be able to get it up and running again

im hoping there is a good old fashioned operator or two who would relish the job

Thanks in anticipation.

In Fortune Town in Bangkok are several high class HiFi shops with the kind of equipment you have.

There is also one of those repair centers which repair any kind of electronic devices. If it's just the capacitors then I am sure they can replace them.

IMHO that doesn't sound like electrolytic capacitors. The big electrolytic capacitors are in the power supply (of the PreAmp) and that is needed for any output.

 

If all worked before your move that also does it make unlikely that the electrolytic capacitors failed. They normally fail because they are old, not because of a move.

 

For me it sound a lot more like a lose connection/cable or a bad switch. Probably you should be able to find the problem with a multimeter.

 

In case you like electronics and are not familiar with Bangkok visit Ban Mo. That is electronic paradise.

Thanks One More ,

the "electrically minded  " has had a good poke about inside and cant find any culprit, the capacitor part was something read on the internet, as a possible.

if you have any name/s of the service places id be most grateful as id like to hopefully contact them, and send it to them if they seem likely to be able to effect the repair.

Thank You.

I go sometimes to Fortune and I saw these shops. But I never visited any of them. I can look when I am next time in Fortune, but that might be some time. Maybe just google "HiFi Fortune" and I guess something should come up.

There used to be a large repair center on the top floor of Old Siam Shopping Center, in Ban Mo and it's probably still there. I think they could fix anything.

You need to take it into Fortune, go to the third floor and walk towards the end where the dealer Piyanas is.  Before you get there, there's a smallish shop on your right selling second hand CDs and vinyl with a repair shop at the back.  They speak English and specialise in the repair of amps.
