6F8G is no good in LP and MJ2. However, the 6C8G works.

Is the 6F8G a no-go due to noise where the 6C8G is OK in the LP or MJ2? (the current draw should not be an issue)

How about dual 6J5G's in a adapter for each channel in the LP or MJ2? I use both of these (w/ adapters) in a VERY basic Garage 1217 amp with a cage to keep them quiet.
This is with a pair of C3G's.

I'm rolling with singles, and have the one I posted earlier in the thread. I'm REALLY digging this tube as it burns in. Almost at 100 hours. Prefer it by a good bit over the a2900.

Thank you @Guidostrunk as I wanted to check to see if you were bidding on it before I bid on it, As I respect and don’t bid if another forum member is bidding on tubes! Very interested in these as I really like the B309 version I have!

6F8G is a no go in the mj2 and Lyr 2 due to the heater current (600ma, way above the 415 limit on the mj2/Lyr2). 6C8G are 300ma.

Dual 6J5G will also draw 600mA as each one is rated for 300mA. You'd need an original Lyr for these.

Ah Grasshopper, 'ma' is the value that I missed. I saw .3 amp (6J5 x4 using 2 dual adapters for L / R) and .6 amp (6F8 x2 adapters for L / R ) and thought it was only a total of 120ma but it is actually 300ma X4 and 600ma x2 for a total of 1200ma? ...........WAY over!!!!!

Thanks for the math lesson, AC!

So much for thinking it was possible to use dual single plate tubes in the LP or MJ2. Not even close!!!

Wax on, wax off. To complicate things a bit, it's not total heater current for all tubes, but just for one channel. If you could find single triodes that were around 200mA each you'd be in range.

You guys have done a ton of trial and error and I just need to K.I.S.S and stay with single tube w or w/o adapters. Step away from the Faraday cage............

Thanks!!!

I haven't seen that show in ages! It sure made me crack up back in the day. I haven't tried a Lyr 1, but it would accommodate these tubes you speak of, maybe someone could chime in if that'd be a good option...

@nwavesailor and @mattrudy80, love the old tv show and movie references Kungfu, Karate Kid, and Sanford and Son! @nwavesailor how do you like your Oppo HA-2 portable dac amp? I have one for my portable cans and I really like it!

I do like the Oppo HA-2SE and am using it now mostly as a line out DAC into the amp.

The Oppo is a good little dac/amp!

In the future if you want to get another dac for your home setup, most of the members here, really like the Schiit Gungnir/Multibit it is a little more money at $1249 the non multibit version is less at $849 https://www.schiit.com/products/gungnir

For myself I am using the SMSL SU-8 which is a good little dac (it’s Balanced) and can be had for around $250 on Amazon
https://www.amazon.com/dp/B07DQDNF6S/ref=cm_sw_r_oth_tai_FT-0Cb7DBBZQY

Another really good dac/amp is the RME ADI-2 DAC (tons of setting options) it’s around $1100

Also how is the reading coming along? As AC was saying there are several pages you can skim through as the post will be off topic but most of the time still a fun read!

Oh well now I have a backup pair as I really do like the pair I have!
IIRC the blue paint were used in aviation which is a plus for me with my interest in aviation! (Looking at the positive side of it)

Only one backup pair? Man, you really live on the edge. A dozen or so backup pairs are kind of standard.

I thought the cage was there to keep the likes of @TK16 from pilfering while visiting. So it's not just a security measure then?

You need a proper balanced DAC like a Gumby to hear the GEC A2900 in its full glory bro.
