Earlier in the thread i think people used 6SL7 with no ill effects so 7F7 will be OK.

7AF7's do seem scarce though and a little more pricey than 7N7.

@ilikepooters when you used the genuine melz 1578 in your lyr3 did you notice any differences between low gain/high gain ,and which was better in your opinion?

 

[Zachik]

Correct. You can put a 7F7 in the Lyr without causing any harm to the amp (same pinout and only half the heater current draw of the 7N7 / 6SN7), but whether it will sound good is a question I can't answer. I have a boatload of 6SL7's but haven't ever tried any in the Lyr. Mostly because I'm lazy, and partly because that would require additional work which scares me because I'm lazy.

Yeah - I know how additional work would scare the hell out of a lazy guy
Joking aside, if you (or anyone else) finally try 7F7 or 6SL7 - please report back. @Ripper2860 is anxious to buy every 6SL7 and 7F7 tube on eBay...

My Lyr 3 tube purchases have been reduced considerably since getting the Valhalla 2 amp. Other than my recent Brimar purchase, acquisitions have mostly been towards 12AU7 and compatible tubes. Still love my Lyr 3, but VH2 has me smitten, as well.

For me i found early on in owning Lyr 3 that gain setting makes no difference to me so have been using high gain since then (planars), never tried low gain with the 1578.

Something else i find weird though but could be my imagination, sometimes when volume pot is lower than i would like for headphones i turn up volume on PC (software) and sometimes seems to make it sound better, only happens because i'm too lazy to get off couch to change proper volume pot So Lyr 3 could be sensitive to input level or could be my imagination.

Hmm I see, as for it maybe sounding better with digital volume turned up could just be the age old debate between digital/analogue volume control, and how it's implemented etc.

I usually just run my software volume as -3db to account for inter-sample overs.

I prefere Low gain for IEM's, but for headphones too, 'cause the volume is more granular.
Today, after around 4 moth listening I've swithced out the Psvane CV181-T-MII MarkII Series 6SN7 for the BRIMAR 6SN7 GT made in 1959 in smoke version. And resolution and soundstage are incerdibles, simply amazing, and a bit mezmerizing for a tube rated 59 years old

Yeah buddy! The Brimar 6SN7GT, takes the Lyr 3, to another level.

Any thoughts on these? Purchased locally this afternoon. All have been tested. Just want to make sure they are okay to use. Thanks in advance.

Nice boxes.

Assuming they're 6SN7's? If so, yes they're OK to use in the Lyr 3. If you forward some pictures of the tubes themselves it might be possible to give you some more info. There are lots of variations in the Sylvanias and RCA's. Probably with the Raytheon's too, although I only have a couple different ones of those (one sounds quite good, and the other is pretty nasty).
