Is there a place that will test my Amp tubes??

For $600 this might be worth it.

The MaxiMatcher Digital Tube Tester is a compact precision measurement station for the test bench or sales counter. It's designed to test power tubes for the electrical characteristics of Plate Current (Ip) and Transconductance (Gm). Any of the standard octal-base power pentodes common in today's audio amplifiers including 6L6, EL34, 5881 and 6550 can be tested. With optional adaptors the MaxiMatcher will also test EL84 nine-pin miniature pentodes, Novar power pentodes, 2A3 and 300B power triodes, EL509 plate-cap pentodes and many others.

The MaxiMatcher is used by the audio tech, music store salesperson, or audiophile enthusiast to quickly test a tube for operation and quality. Start by placing a tube in the short circuit test socket and you will quickly identify the culprit that's been blowing all those fuses! The MaxiMatcher can be used to precision-select loose tubes into accurate sets for mounting in power amps, as a point-of-sale aid in selling matched tube sets or for verifying customer tubes at the sales counter.

The MaxiMatcher tests up to four tubes at a time, and has a separate socket for short circuit testing. Easy directions for use are provided right on the top panel and the layout is clear and intuitive, making the MaxiMatcher simple to use and easy to understand. Separate selector switches for Bias Voltage, Plate Voltage, Measurement Function, and Test Socket Select are provided, along with the proprietary SmartFuse high speed protection circuit, indicators and a mains switch. All test data appear on a large, bright 3.5 digit LED display. Digital measurements are made by a proprietary sampling A/D converter allowing high resolution measurements.

That's the one right there, I was looking at that too, but the price...yikes!!
Guess if you plan on running lots of tube gear , it's justified.

I don't think he want's to buy a tester, he just want them tested.

I know. I'm hoping that if someone has a tester, they will volunteer their time to test his tubes. The first one at c. $600 might be worth owning if you have enough gear to justify it.

Yes, it would be nice if someone can volunteer however, I myself is considering the $600 tube tester. Where can I buy one?

I don't know what the MA2275 costs, but if it's $6000, then the $600 tube tester is only 10% of the integrated's cost and would be well worth owning to keep that or future tube components in top shape.

You're right. There are lots of testers on eBay for much less money.

Here is a nice EICO unit....pretty damn good since it has been refurbed and calibrated. NEVER buy one where the guy says his uncle was a tube nut and passed away, blah blah...generally these units are not working, they bought it and trying to pass it on..But if you can find someone local it would be better...and cheaper...LOL..call some electronics shops...sometimes they still have the testers around...
