We hope you can keep up a good work Justin.  I own number of highend gears from various manufacturers, and the craftsmanship on yours are the best by a wide margin.

I've only three headphone amps, but they were all from Headamp, on a different headphone site though ( I stopped going on that site sometime ago ) I got comments saying Justin must love people like me. I guess those that made the comments didn't realise how Justin works, but I do.

Thanks DG

 

And a special thanks to Justin.  A man of few words and lots of talent.  This will be my third Headamp amp.

folks, newbie question.....what would be the tell tale for a tube thats approaching the end of it's life? I had the amp for 1.5 years and roughly clocked in 1,500 hrs.....maybe its time for new EL34 ??

I would define professional as someone who is commited to providing his customers with a top quality product and is not willing to take any shortcuts even if that would make his life easier. Thanks Justin for doing that and for being a professional.

The BHSE I have on order is my first Headamp amp, but I am certain it will outshine my other amps.

Great question and something we all will be dealing with at some point.  Using a tube tester would work if you compare the old tubes with new EL 34 tubes.   I read something the other day that said tubes usually don't fail but rather just wind down very gradually over time such that the listener may not notice the decline in sound quality.  One way to judge this would be with a reference recording that we "know" doesn't sound right any more.  A better way might be to compare the old tubes with a new set.  If the new tubes sound significantly better then just keep the old ones as backup. Otherwise use the old ones and test again in 6 months.  This is just my guess maybe there are better ways to judge these things.

Not my own info, but info from my dad, who has a background in EE & physics and went to college & grad school in the 60s (you know, when tubes were more prevalent than they are today), and saw my BHSE once when he visited: tubes should be replaced when they start to look "burnt out" near the top.

This is really useful information for people like myself who don't own a tube tester and don't have an EE degree. Thanks.

Heads up...anyone who when to university for electrical engineering from the 1990s and on won't have any knowledge of tubes. They're simply not taught in school as the world has moved beyond tubes (save for die hard audiophiles).

It's not the lack of tube education that should hold you back...it's saying adios to your life for 4 solid years! I loved not having a life so much I hung around for graduate school...thankfully a year into my Ph.D. I came to my sensibilities (that and my wife and I were sick of the utter poverty), so I joined the workforce.

I was in university for 10 years... I feel your pain.

Biomedical Science and Architecture, but this is getting OT. It should be in the thread "Stupid things I've done".

:p
True enough...I just wanted to ensure that people realized that essentially engineering schools don't teach about vacuum tubes anymore.
