Echo tubes are Intens 4G fallouts just like commercial spec pinnacles or commercial L3 tubes are to mil-spec tubes. If you know this and pay accordingly shouldnt be a huge issue. Harris and L3 have sold commercial spec tubes of various grades (good to bad) for many many many years I fail to see how Photonis doing the same thing is a issue?
Heck there’s a bunch of L3 commercial spec filmless running around out there right now most with issues of some type ( as stated above didn’t make mil-spec) and most dealers give reduced warranty on these systems as well.
The issue if any too me is if a dealer miss leads a customer to want they are purchasing, overcharges for the product or flat out sells a B grade tube as a grade A commercial spec or mil-spec tube..
I’m sure there are ones that have issues/blems etc etc no different than the commercial spec tubes L3 or Harris sells also. I’ve seen plenty with issues over the past two decades many flat out ugly image wise. Heck I just had a brand new L3 WP filmless develop a bad emission point first 25 hours of use it’s under warranty so will send it back in sh@@ happens.
If you buy anything other than full milspec tubes it’s nice to get hand picked and a decent warranty. It’s been my experience tube failures are rare commercial or mil-spec and the ones that fail most die early in their life. I know you dealers see more tubes than me in the past 25 years, but that’s been my experience as a NV user.
I’ve noticed a lot of dealers sort tubes and charge accordingly. Even seen echos low and high prices depending on grade I’m sure they are ugly ones and nice one just like other commercial grade tubes.
Folks you get what you pay for be it milspec or commercial I’ve bought NV from many places always found this to be true. I’ll give TNVC credit while not always the cheapest price the NV I’ve bought from them has always been grade A tube wise— hence you get what you pay for
My full spec Intens is really clean just a couple tiny tiny grain of salt size specs with a touch higher gain number. Really like this tube overall just excellent screen cosmetics like the old mil-spec ITT tubes many many years back it’s puts a smile on my face. It wasn’t cheap also and compared to the Echo’s it doesn’t have those pepper size flakes on screen.
L3 filmless mil-spec will out perform them along with most every other type of tube made. Buying another filmless WP 20UA tube myself when they arrive instock at my dealer waiting sucks.
I have no plans to buy another echo or Intens anytime soon infact the L3 filmless 20UA will be only thing NV wise I pick up for next 12 months . I’m pretty picky and I’m real happy overall with my Echo’s and my Intens full spec tube.
I also haven’t seen or spoken too any Echo owners disappointed with their purchase did a lot of research before buying my first? Most seem to be happy with the performance to price paid and don’t claim them to out perform Filmless or have better screen cosmetics than a mil-spec tube. It’s just a money to performance level thing just saying guys sometimes a ford get you there while a ferri gets you there in style if you got the extra cash.
Commercial tubes be it Photonis, Harris or L3 only make since to me if pricing,cosmetics and performance level makes them attractive to a buyer. Other wise I’ll go Mil-spec all day long it’s more predictable for a buyer to have a idea of what they will receive overall.
