So the amp arrived today. I got it set up, turned it on and no sound. I then noticed that the 6C33C tubes were not lit up. I shut it down and turned it on again and slowly the tubes came to life. i had it playing for about an hour and the sound slowly faded as the 6C33C tubes shut down. Any idea on the cause. I am waiting to hear back from the seller and I'm guessing I will need to send it to Craig to repair.

Sounds like something in the heater supply came loose during shipping. Since both sides of the tubes failed together, my best guess would be that it is likely a wire connecting to the regulator. If you know a decent tech, it may be something that can easily be repaired.

Mike, Ron (HiFlight) is good in electronics but he lives in Fort Myers. If you would like to contact him send me a PM for his phone number. Cheers and good luck.

It was the pins for the ps umbilical. I should have known since I've owned a few EC/Moth products. The seller told me to try and pull out the pins and it seems to have worked. Thanks again for the help.

Miguel, I will. I have Jp's modded Melos Gold to compare this weekend. The ZD is a beauty.

Mike, I still have the MPX3 that was further upgraded after I bought it from you and it was also upgraded/fixed by the good Doctor! If you want to borrow it let me know. Cheers.

Should you decide you want to keep the ZD, you may consider replacing those crappy plastic

power connectors with the amphenol military things. There is a size that fits the chassis holes

directly. About $200 in parts plus the labor to rewire everything.

I was wondering the same thing. The ZD is one hell of an amp for what I paid. Now I just need some LCD-2's to compare to the HE-500's that I am really enjoying at the moment.

Miguel, I forgot about that amp. I always liked the MPX3. I may take you up on the offer.

KG, you assume I have the skills to make that happen. Wait, you know I don't have the skills to make that happen. I will keep it in mind should this problem happen again.

I can't believe I am listening to headphones again and enjoying it.

Currently there is this on the 'gon. $1650 with some operational problems that I'm sure would be easy to fix. I need to finish a few DIY projects first, but god damn this looks like a good deal. Does that seem like a good price? Gah! Why am I asking? MAKE IT GO AWAY!!!

I would have expected that an amp like the Zana would already be using the good amphenol mil-spec (did I really say that?) connectors at that price point. Didn't Mike (absorbine) have that same problem with his at a Chicago meet a few years ago?
