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,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.

Bluebull,

I'm a fan of a lot of gear and very aware of Sam Tellig's affections. I'm also glad you're happy with your choices, sorry if I misunderstood a few of your comments. We both know this kind of thing can happen with any piece of gear, it shouldn't, but stuff happens. I think we'd both agree at this point that Washline needs to get the amp to an authorized service center before somebody screws it up further.

Best Regards,
Merganser
Why don't you have the dealer who sold it to you off the internet get it fixed? Or is this guy not an authorized MF dealer? This sucks. You bought it new, it should be warrantied.

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

Dear Wasline,
It is called 5703 tube. Tube world sells them for 9.99. They are still used in microphones. Frankly I would be suspicious of the tech who told you they went bad. If they did there is probably something very wrong with the amp.
