Right driver in my HD650 busted

[postjack]

I'm working on something on that front Jack, if it pans out I may have a deal for you...

sweeeeeet! no way I'm paying your 0% processing fee though.

it was definitely the tube. after I waited for cool down and rolled in a new output, my ksc75 sounds splendid. this is the second time I've blown a driver with a bad tube. makes me want to get a tube tester.

Or go SS (says the guy with a tube amp).

[postjack]

after a few years in this hobby, I think it's safe to say I'm a tubes guy. I've owned some awesome SS gear, but tubes always pull me back, even with all the bullshit hassles. I have yet to try tubes in speaker amplification however.

WANT THAT TESTER

[aardvark baguette]

I've never even touched the tubes in my amp, much less change them.

I don't even remember what kind they are.

Now I'm scared.

Hell yeah!

Boy, and if you don't... probably calibrated an everything.

Indeed, when I bought it (about 2 years ago) it had just been serviced and calibrated. I've also got both the original and a very extensive aftermarket manual for it.

I've got my eye on a couple of things and if they pan out I'll let head-case know first.

I think postie and I are going to have to mudwrestle for that one

Would it be bad form to show my back up tester?

[Dusty Chalk]

Doesn't do curve traces.

Doesn't do curve traces.

Uhhhh, I'm only aware of one that does and it's safe to say that I'll never be able to afford it.

don't Google around for DIY options then

Here's a different approach though:

Tube Tester analyzes tubes by Transcendent Sound

I've developed my owm method, and it's more accurate than those testers too.

I throw the tube on the ground as hard as I can, and depending on the colors of the explosion I can tell you wether the tube was good or bad.

got the drivers in today, that was fast. later tonight I'll attempt to dismantle them and pop these in. then begins the 8,000 hour burn in procedure; white noise through the ha-2 at maximum volume.

That will be a fun 11 months or so

You know it's going to be asked- hour by hour updates please!

...with percentages if you don't mind

[swt61]

...and graphs, in color.

With onomatopoeia and alliteration.

Perhaps with a pinch of postjackian humor.

That was really easy. Props to Sennheiser for a very end-user friendly design.

1. Pull off the pads

2. Snap off the headband

3. Pull off the grill

4. Pull out the bottom part of the headband ring attachment thingy.

5. Put in the new driver (Sennheiser calls it System 300R, and system better describes it, since its a driver in a housing with the input jacks for the senn headphone cable connectors)

6. Reassemble.

Interesting side note: the drivers I received are the newer, white drivers, and the old drivers were the black ones. Whether the drivers are truly different other then the color is a subject best left to one hundred million HF threads, but the difference in sound to me seems readily apparent. Bass has tightened, and both treble and midrange are slightly more forward. Of course this could just be that we're dealing with brand new drivers.

So without further ado:
