Does anyone know if the Garage1217 12AU7 to 6SN7 adapter can be used directly in the Vali 2, or do I need an in-between 6DJ8 to 12AU7 adapter? The description on the website says that 6DJ8 will work, but when I emailed the guy in charge he sent this in response

"It depends on what voltage the amplifier you are using is running. If it is actually 12v then it is a no go. If it is 6.3V using the center tap for 12au7, then it can work for 6dj8 too. "

Does anyone know what voltage the Vali 2 runs here? I'm asking because it appears my 6DJ8 to 12AU7 adapter got sent to my old address and I doubt I'll ever see it. I already have the G1217 adapter for use with my Crack, but if it could pull double-duty with the Vali 2 that would be excellent. And I am IMPATIENT to move on from the stock tube! I have a handful of 12AU7 and 6SN7 sitting around just waiting to be useful again....

The Vali does run 6v heaters. But since the 12au7 tubes needs to be wired differently, it might not be compatible directly. To be clear, I don't have the G1217 adapter so I can only speculate, but from the info I've gathered you'd still need a 12au7 to 6dj8 adapter between the amp and the G1217 adapter. I grabbed a one of those 6sn7 to 12au7 adapters off ebay and for kicks tried it directly into the V2 (needed to remove the top cover for it to fit). I got nothing. The tube wouldn't even light due to the heaters being connected to different pins - I needed a 12au7 adapter too. That said if you already have a bunch of 12au7 tubes why not buy a 12au7 adapter too. I'm sure that double adapting can create issues with noise, etc. but you'd still need to use a socket saver at the least since none of the 6sn7 adapters will physically fit into the V2 without removing/modding the case.

I suppose you could always remove the top of the amp and try plugging in the g1217 adapter and tube like I did and see if it works. In theory nothing bad should to either the tube or amp if it doesn't

I use 6sn7 fine with my vali 2. You use a socket saver then a 6sn7 to ecc88 adapter.

I use that 12au7 adapter instead of the socket saver and went for a 6sn7->12au7 type adapter. Whether @ohcrapgorillas would need to use the same 12au7->6dj8 adapter I need is the question. I suspect those g1217 adapter probably will (even if for no other reason than sizing - 6sn7 tubes have a much bigger diameter and won't fit the case, like your pic shows)

 

[ohcrapgorillas]

It did not work. sad trombone

I did end up ordering a new pair of adapters for 6SN7 and 12AU7 but I will have to bear with the stock tube while I wait for them to arrive from Hong Kong. I have the socket savers already.

 

[Mr Trev]

I thought that might be the case.

Here's a bit more info on how the adapters are wired to explain things…

I have a lot of time with the Reflektor 6m3p-3 and was sent a Foton 6n3p so I could compare the two. Thanks @bcowen I truly appreciate it. It is burning in a bit but here are some pics.

Wow! Once again, some beautiful pics, Chef. I'm pretty sure the Foton didn't look anywhere near that good in my Vali. We're all eager to hear what you think of it once it gets some burn time.

On an unrelated note, has anyone seen @volly? Has he gone missing? Maybe he's in such sonic bliss with his new amp that computers and forums have become irrelevant?

All good @bcowen, mate this amp I tells ya!!

Funny thing, just rolled in the Canadian 6Bz7 stock tube that came with the Vali 2 in to the MCTH, ummmm wowa...like...nobody in this thread loved that tube in the Vali 2 but it sounds so nice in the MCTH. Philips SQ not so good in the MCTH but the EH 6922 tube that comes stock with the MCTH is a delightful tube and well implemented in this amp. Going to try it in the Vali 2 if I can spare a moment from the MCTH. I wonder if it's worth springing for the Gold pin version?

6Sn7 tube prices are starting to inflate all thanks to Lyr 3 owners?!?

Uh-oh. Looks like 6BZ7 prices are going to inflate here shortly. Lots of RCA's, GE's, Raytheons, Sylvanias available on Ebay....for cheap. Maybe I need an adapter for the Lyr3.

Threw on the Jan 5670w tonight to compare to the two 6n3p I have and thought I would post some pics as this is the most tube glow I get out of any of my tubes.

 

[volly]

Looks bloody marvelous! How does it so far @chef8489?

More tube porn. I love it!!

 

[chef8489]

The mids and and bass are better on the 6n3p the treble is more prevalent and detailed on the 5670w with the mids a little more recessed and blend in with the bass a bit.
5670w ,ales the Lcd2c more neutral
6n3p make the bass hit harder and allow the mids and bass to come through better on the LCD2C

Anyone tried this in their Vali2? Its a 5760 with a machined 6922 adapter with noise filtration of heater supply?
