Krell KSA 80 110v - 220V conversion. Need help

[webercarbmann]

Hi all of you.

I need some help regarding a Krell KSA 80 amp that i am bying. It is not the KSA80B but the US non ballanced version. The amplifier is in the US and made for 110VAC operation. My question is simple. Is it posible to convert this amplifier to 220-230VAC opearation just by rewiring the primary section of the mains transformer? Also it would be nice to know if other Krell amplifiers are made as "multi voltage" units. Some ML amplifiers can be converted just be changing the wires of the mains transformer. (23.5 can)
Anny info would be great. We have tryed to contact Krell by phone and mail but the company does not seem to be that service minded when it comes to questions about older products.....

Thanks for your help. Peter Jensen.

Here is a link to the
KSA-80 Service Info at Don Mclean's web site. Its about the only info on the KSA series that I am aware of. Try to match up the wire color code on the trafo with those in yours. BTW: The 80B is alot better amp! One of my absolute favorites!!

Good Luck,

Mark

Hi,
there were a couple of thread on converting some modern Krell to UK voltage in the last year.

It appears that Krell have put in some anti tampering circuitry to shut down the amp (and other ancilliaries) to prevent grey imports where the mark up is very high.

I do not know if any of those thread conclusions apply to your amp.

I can guarantee you that neither of the KSA-80's would shut down!!
