The cathode voltage is wrong - 12.6V.

The Lyr is designed for 6.3V tubes.

PCC88 isn't 6.3 and works great too, but sure 12.6 is bit more off :D

E80CC can work at either 6.3v or 12.6v, depends if the heaters are connected in parallel or series. Just the pinout needs correcting.

7V is one thing; but I would check with Schiit on it before popping in a 12V tube.

Hi, cg to new purchase ;) hope you will enjoy your Lyr as we do basshead.gif

 

As for tubes, I think it depends a lot on headphones you are using with Lyr.

What tubes did you get with it and how do you feel about their sound?

post #6698 of 8735

Tuna47 has the GE tubes, listens to jazz, rnb and blues, and has HE-500 headphones.

 

So something that would work well with that combination.

Not without modifications, if you plug them straight into Lyr something will go pop i reckon.

 

I started a thread in the DIY section, it seems pins 4 and 5 need wiring together and connecting to just one heater lead, then wire pin 9 to the other heater lead, that's if Lyr supplies AC to the heaters.

 

If it's DC to the heaters it gets more confusing, 4 and 5 need wiring together again but attaching to the positive heater lead, and pin 9 to the negative heater lead.

 

I need to get myself a multimeter so i can look into this more, oh and a couple more cheap chinese socket savers to experiment with biggrin.gif

What do you guys think about these -> http://www.ebay.com/itm/2x-ECC85-RFT-TUBES-MATCHED-PAIR-New-Old-Stock-/251250671744?pt=Vintage_Electronics_R2&hash=item3a7fb50080

 

Don't have any ECC85 at home, so I would like to try some and don't want to spend fortune on them.

This is the only impression i could find about RFT ECC85.

RFT is a disappointment.
They have a superb stereo separation,(i don't need it, if there are other tubes showing a stage as a whole), they have no depth, odd two dimensional presentation, they superbly shows micro details, but they sounds boring, graveyard boring.
They have strong and precise bass, but it is bit lifted to the mid tone area, good for people preferring mainstream car audio sound.
Good tubes for audio masochists. Pitty, they have also very good gain.

 

That person seems to like the Tungsram ECC85's though.

Oh, thx for fast info :)

 

Does one tube bahave same way in different amplifiers ? I'am asking because the first link is not about Lyr.

 

Btw does 6N2P work fine with Lyr ?

Lyr is really designed to work with E88CC/6DJ8/ECC88 type tubes and is set up to supply the correct voltages to them.

 

But running tubes out-of-spec can also sound good, like Lorenz Stuttgart PCC88 is a 7v tube, but a lot of people believe them to be the holy grail of Lyr tubes, even though Lyr isn't designed specifically for that kind of tube.

 

If an ECC85 sounds good in one amp, it might sound rubbish in another that wasn't designed for it, or it might give a better sound. only way to tell is to try it.

 

6N2P has the correct pin-out, but is really low gain, might be garbage, not tested them myself.
