Problems with my Tri-Vista 300--Need some help


My new Tri-Vista integrated has worked beautifully for a month, but yesterday, for the first time, I discovered that no sound is coming through the right terminals into the speaker. I tried shifting speakers and cables around and found that it has to originate with the amp. The amp has two sets of binding posts, but in changing the speaker cables to either of them, I've still gotten no sound out of the right side. Could this be a problem with an internal fuse, and if so, and since I have no MF dealers here in Korea (I bought off the net), what might be my options in terms of getting the amp repaired? Any suggestions?

Sorry to hear,see no alternative but to have it fixed by official MF importers,have you contacted them ?Dont think 2 tubes in a month is acceptable....Hope Sam Tellig of Stereophile, is reading this about his beloved brand....
Hope you get it fixed.

Problem with MF,reliability.Perhaps small problem,open up the amp and see if fuse or fuses still intact,if not ,easy to repair,just check the fuse rating on the fuse(My Pathos Logos has 6 fuses in total).Check the minuature tubes.If cant find problem there,try to get fixed locally,must be some reputable repair places in your Country.Try to avoid sending to another Country due to cost.Try not to send to MF as may refuse to repair as bought "Grey ".Dont know what their policy are.
All amps basically work on the same principals so should be easy to solve the problem.
Good Luck.

Sorry,but you are a bit oversensitive regarding my contribution.Seems like you are a MF fan,nothing wrong with that,they make good stuff.
Now,concerning my "little digs" , as you call it.One months use before repairs are needed,is not acceptable,for any piece of equipment.This is an expensive amplifier.Sam Tellig is a big MF fan, go and read a bit...it is a fact."Belie your envy",no not really,very happy with my equipment.Not likely to ever go to MF as the local importers pricing is way to high and the back up/service is also not good.
So not trying to second guess Washlines purchase.Fact is it is still not working...and I really think he wants it fixed.

So,actually we are really batting for the same team....

Washline,I hope you get the amp fixed,soon.

Hope this clarifies matters.

Will be an expensive endeavour to send back to the net dealer,whether guaranteed or not,as the amp is neither small or light.Still think the best to have it repaired in Korea by MF importers,if represented there.Do not know if they are or whether they would repair a "Grey " import.Still there must be a capable amp repair shop there.Perhaps should try someone else,locally.These things happen....(My Merc E320 needed a new engine at 28000 km ,factory fault.Should not happen but does.Sold the Merc.)

Let us know how you are progressing,Washline

But cant MF supply you with the spare tubes ? I thought they had one extra set per amp manufactured or was it the Nu Vistas ? I cant remember....Perhaps you can try Wim Bouwman at Mr Valve in South Africa,my local tube supplier,chances are slim but I think worth a shot ...mail is bouwman@telkomsa.net
