The truth may be that there is a 6A winding on the main transformer so together they give 14A. Perfectly logical way to do things but since Mikhail seems to be incapable of telling the truth he spews some BS instead. As for a response, why don't you ask him if you amp has in fact 6 channels... it has 3 double triodes after all.

Sounds like the usual Mikhail BS to me. He could have wired it up so the primary is setup for 230v and the secondary for 12.6v which cancel out each other for a 6.3v output but the windings can only handle so much current. Somebody should really teach Mikhail the old saying, "when in a hole, stop digging!!"

They certainly aren't bad and I love my "obsolete" dac's. The APL isn't all that bad though

That's where the ESP950 comes in.

...and slowly, but surely, damages the diaphragms in his phones. "My amp is so good that the phones can't handle the level of awesomeness..."

Happy birthday dude!!!

Not helping... The SR-007A will match my BHSE though...

That's what Marc said they do a few posts back.

That's Bob Anderson or randerson(some numbers) as he's known here. I've started to chant, "I don't need a Mk2... I don't need a Mk2..."

i.e. arcing between the wires. Try to arrange the wires for maximum separation and even insulate the terminals or just remove the cable and send the phones to Koss.

That wouldn't happen to be an ET-1000 with an ever so sexy gray adapter cable...?

That removes one nasty possibility. Didn't you just split open the housing and replace the cable or did you remove the drivers as well? I don't see how dust could infiltrate it if you just opened up the housing.

The gap between the stator and diaphragm is only 0.5mm and the dust can be much smaller then the to cause a nasty squeal. It is also on the inside of the driver so you have to take it apart completely. One question though... when you were soldering the wires, did you have the drivers completely covered so no excess flux could burn its way through it?

Might not be dust but the terminals on the driver arcing. If it is indeed dust then taking the driver apart and blowing gently on the diaphragm and stators (remove any residual charge first by shorting the Stax plug) should get rid of the particle.

Each 6528 needs 5A of heater current so 14A should be enough...

If he's simply using the 8A transformer to supplement the filament winding on the Plitron then the 14A figure would make sense.

Spiraled works very well and is dead easy to make.

Allied Electronics part numbers 78-S6S is the socket 86-71-6S is the plug Been there done that... I wouldn't recommend it though as it sounds horrible. The Koss unit is the ultimate statement that voltage swing isn't everything.

Sadly all impressions are lost after years of alcohol abuse...

Sounds like I could use a pair up here. I could argue that they are in fact used for heating and get a discount on the electricity.

Ahh the days of misspent youth watching UK tv on satellite...

None that I know of

Speaking of 6c33's... That's a mono amp

Sucks is a pretty big understatement here... webbie64's set has been recabled by APS but an adapter is easy to make. The WPI connectors are back in stock at Allied so just order up a Koss extension cable and start soldering.

Andy, those issues that Kevin linked to have been reported by other owners as well and are caused by the filament wiring. You far from the only one with "faulty tubes" according to Mikhail. Last I heard (last night my time) the amp will ship as expected.
