I got the HE-6, and am running it from the V800 + vintage integrated Sansui.  I'm more than happy with the results.  It outclasses the HE-500 in almost every way, minus the silky smooth vocals that I may miss with the HE-500 + LF339 combo.

I think for now u should wait for Yuking and use what he sends as long as it is under warranty.
 

Hi Wall-E,

 

Vashay/Dale does make this value and this is probably what I'm going to use, unless Yuking comes back with a much better solution than currently provided.  At present, he offered to replace the defective adapters and the resistors for free, if I pay $50 shipping.  This seems excessive considering these are warrantied items and (the resistors at least) can be had for $5 + $2 shipping locally.  I've seen socket adapters for cheaper, as well, though I'm still looking for a B9a to Octal.

 

I'm hoping this is a misunderstanding of some sort, as I know he's provided better customer service to others on this forum, but I can't see paying $50 for a resistor that can't be worth more than $5.

 

BTW, if anyone knows where to get a B9a to Octal adapter, let me know, otherwise I have some barely used EF80s to sell.

I'm assuming you're with La Figaro.  I realize now that the adapters weren't technically part of the unit, I was under the mistaken impression they were covered by the warranty.  I opened one up and eliminated the hum, but am having trouble keep the wires in the correct position when I reassemble it (I could probably get it if I work on it long enough), the other just won't work at all, though.  I tested both with all four EF80s and when I have the one adapter working, they sound good, so its not the tubes.  I think I'm just going to give up on the EF80 family, though, and go with an octal tube.  The adapters aren't worth the trouble and there are plenty of good sounding octals.

 

I need some supplies, like solder wick, so its easier and faster for me to get the Vashay/Dale resistors than to wait for the stock pair.  I'll let you know how this works out--I'm don't have much soldering experience, but my friend is an electrical engineer and loves these types of projects.  It may be a couple weeks because he's really busy, but he said to bring it to his workshop and he'd walk me through everything.

Are these pictures of a new product?

If I remember well this was a custom project for a customer. But I'm not sure

I think I've got one of my EF80 adapters working.  The other is only giving me static and I'm not quite ready to give up on it yet.  According to everything I've read, pins on octal should be soldered to same pin on B9A and the 9th pin is just left unused.

 

When I look at the broken adapter, however, its missing a couple cables in addition to the extra pin.  I'm assuming these are ground pins and were left out for a reason (or could be the reason it doesn't work?).  Anyway, if I either rebuild this adapter or made a new one, am I correct in matching each pin to its counterpart or are there pins that shouldn't be connected?

 

I've tried to see the inside of the working one, but have too many cables and not enough slack without completely taking it apart and would prefer not to mess up the working adapter if I don't have to.  Thanks for the help.

Actually, assuming I can't get the adapter working, what octal tube would you all recommend with 6AS7Gs.  I'm looking for something warm since my Beyers are pretty cold by nature.  I've already gotten a couple suggestions, just wanted to open the question up to a wider audience.  Once I get the amp working right I'd rather keep it that way and not screw it up by mis-wiring adapters since I can't find a good schematic.  Thanks.

 

EDIT:  I think I'll give a pair of 6SJ7GTs a try.  I gave the adapters one last try and they just won't work for me.  It isn't worth it to keep trying to get them working.  If anyone wants one of the pairs of EF80s, PM me and we can work out a price.  They were NOS Telefunken.  Now I suppose they're slightly used, but one pair will have about 8 hours on them, the other pair will only have a few minutes.  I haven't kept track of which is which, though.  If no one contacts me in the next few days, I'll put them up on Ebay.

Thanks, but I actually typed that wrong.  I've got a couple pair of 6as7g's.  I'm looking for which type of tube I should use as an input tube with them if instead of EF80.

Like he said: RCA or Tung-Sol 6SJ7(W)GT
