Anyone Here Ever Purchased A Tube Tester?


Once or twice a day a tube sputters for a brief second in my Audio Research Reference DAC. The Reference DAC is connected directly to my amplifier and it also serves as my preamp. Visually, all of the tubes look fine. Visually, I can’t tell which tube may be bad.

The tubes are:     (4) 6H30, plus (1) 6550C and (1) 6H30 in power supply

Have any of you ever purchased a tube tester to test your tubes? If so, what tube tester are you using?

I just think you leave yourself ’blind’ without a simple inexpensive tester.

For most of us, we don’t know detailed measurements. When something is amiss, quickly check tube: short? strength? strength matched to other ’matching’ tubes?

Buy new or used tubes, test them, supposedly matched tubes, test them.

IF you are tempted by the simple type, like the Accurate 257, I will have my friend check the booklet to verify it can test your tube types.

I look for shorts, and strength on the meter, and if strength matched. As I said, my Accurate Strength always matched the big heavy Jackson’s results, so I gave the Jackson away.

 

I frequently blab about everyone who has tube equipment getting an inexpensive tube tester.

I bought this Accurate Model 257 for a friend.

 

It's results matched the results of my smaller model 157. My Model 157 always matched my big heavy Jackson, so I gave the Jackson to a friend who used to bring his tubes here.

KISS.

I purposely avoid knowing stuff, so I can make decisions that are 'good enough', like a simple tester.

If it sounds damn good, like my Sony xa5400cd player I got with help here, I don't want to know about anything else, unless it breaks. I probably would just buy another xa5400 without even looking at anything else.

I had a big Hickock, and the Jackson I mentioned, never went beyond shorts/strength/matched strength? Big, took more space, heavy, not easy to take to a friends house ...

After 'little accurate 157' simple short/strength answers were ALWAYS the same, I gave both the Hickock and Jackson away to friends.

I have a LOT of used tubes, hundreds, some of them actually new. I test them before giving to friends, or using myself, a few for the 2 Fisher 500C's I'm going to sell if I overcome my reluctance to ship.

I'm between NYC and Philadelphia, perhaps I will try pickup only.
