Zana Deux Problem

Featured Replies

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.

Good to hear that it was something simple.

Good to hear it was an easy fix. No fun to get a new toy and not have it work.

Nice to see it worked out for you Mike. Since you most likely will be selling the amp soon let me know. cool.png

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.

Any idea what's with all the Zanas coming up for sale at the other forum? Funding for the Super 7, I guess...

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.

Mike, you can borrow my LCD2s in a few weeks, after my gathering in December. They sounded great on absorbine Mike's ZD!

Just call me of PM me Mike. I have some older russian 6H8C tubes in addition to a bunch of 6SN7's you could borrow to roll!

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!!!

That one is on HF as well. $1650 is too much for that amp at the prices I've seen lately. I paid less for the newer version, non-SE. Here is a better deal: http://www.head-fi.o...ux-canada-conus

Nice deal. How has that been up for a week with no buyers

At that price, I'd expect it to be without faults.

Who knows? Maybe things run deeper...

One just sold on HF for ~$1300.

There is another one over there going for the same price.

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?

That's what I thought: older model with some odd problems...priced too high... Thank you!
