I live on Australia, so postage from the US usually runs $15 to $20 for a lot of 5 to 7 tubes. An extra $2 to $3 each tube....

Thx... A total of $14 for the pair :)

These arrived on Friday: Wow, they sound amazing!! Beautiful highs and mids, plus deep clean bass you can 'feel'. These are VERY nice tubes!!

Their current amp, which uses 6N6P power tubes, sells for £220 on eBay.... Which is already more than a Mk 9. Given everything we have seen that our LD amps can do, I would find it hard to believe something else could offer the same quality and durability for less, or even 2 or 3 x more expensive!!

I will give them more time. I wanted to listen to some new power tubes with drivers that I am used to. They will come back into the rotation soon.... So far, they sound as described above. After three days of listening to them, that is close of music 30 time....

Last night, the match for my Ken Rad VT-231 arrived and I switched out my 1578s. Very nice sound, but a bit too Bassy (not kick drum bass, more bass guitar or double bass Bassy), which is fine for many. These tubes are sometimes called the king of bass. I like more solid and defined bass. I...

Hi Mordy, You just might enjoy the c3 g as drivers. They do enhance the bass potential of the power tubes and from everything I've read, you like a nice warm sound. I don't think I'll keep them as my primary drivers tho. I really like my 6J3P-E tubes as drivers. Perhaps a bit more detail at...

This is the match for the top left tube: Total cost for the pair: $12. eBay was looking the other way... Very happy :)

Bargain of the century. $6 :)

For example: The first pic is from a lot of 5 6SN7s I bought for $35. These two tubes are both black glass NUs, that sell for $70 to $90 a pair. All were reported as 'test good'. A great deal. The second two are a Ken Rad VT231 and a grey glass Sylvania VT231 I picked up from an estate...

I have bought a LOT of tubes super cheap. I spent a long time poaching auctions on great 6SN7s. If you read some of the 6SN7 threads, you can learn to recognise re-branded great tubes and pick them off for < $15. eBay never sleeps, but it does sometimes 'look the other way'. I have poached...

My three 'new gear' CDs are Miles Davis KoB, Sinead O'Conner Am I not ur grl, and Eric Clapton Undrugged. All slightly different sounds and each beautiful in its own rights. I know each better than any other recordings. Right now, with the tubes mentioned above, KoB sounds sublime (again!)...

My C3g adapters arrived today: Wow, they sound beautiful with the 1578s! Too early for a full review, but I have no doubt this combination could be an 'end game' for many. Full rich sound, with great bass and not much compromise in other areas.

  Yes, the exact ones. From the Ukraine. I have bought quite a few good tubes of that seller.

Real 1578s... Metal base and holes in the plate. Wow, these sound amazing! Great bass, great treble, great dynamic transients (attack) and beautiful voices. Wow. Worth every penny!

Thx.. I'm just interested in learning.

1578s.... Pretty, and sound amazing!! Very nice trebles, with persistence on cymbals plus great defined bass, great energy (attack) on snares and other high energy transients plus beautiful mids (brass, woodwinds and voice). Highly recommended from first hand enjoyment. Ps - make sure yours...

I've looked too.... And the Mk 9 has the best price for the feature set required. However, right now I am happy with nice 6SN7s in the Mk IV. BTW, the LD Mk VI owners threads seem to like the 6SN7 as a driver, despite the lower gain.

What does testing low do to the sound of a tube?

My amp uses 6.3V AC.... Do you have some pics and more info? Thx...

So, here are some pics of the CBS tube compared to a 55 sylvania GTB: From the front, the triangular plates are identical. From the side, there are five holes of identical size.... But the flaps made by the hole punch are on different sides. Other than this very minor difference, same...

Yes, that is the first thought that entered my mind too!!! PS - yes, I'm doing my homework... Reading the entire thread from the start...

PS - nice new amp TD!

Hi everyone! As I mentioned in this previous post, I have been playing in the world of 6sn7 power tubes. Wow, some of them are just amazing in the LD. I still like the drivers I mention above with rhe 6sn7s, but my new favourite power tube is the Tung Sol 6sn7gt 'Mickey Mouse Ears'. Beautifully...
