Wow 8 pairs! Thought my 6 pair at 1 point was excessive. You try them in the LP yet?

Not yet. I was trying to avoid adapters, but i think that might change. A while back, when i had my Valhalla 2, they were amazing, so i stocked up. I also have a lot warmer headphones these days, so i dont really need anymore warmth, at the moment.

I believe you were the one, a while back that recommended them to me.

Sounds like you hate them, feel free to sell them back to me at 1/2 the purchase price. I don't have any more WE 396A for sale sold half my stash already. Enjoy them tubes bro, pleasure looking at them in the dark, like 2 night lights in the room.

You're the man! Yeah, I hate em enough that I think I'll keep em for a while.

Got any codes etched or written on them? I think Valvo is a rebrand of Philips, so hard to say with just the name. If so interesting, that they can sooth the HD800. I always thought the philips e88cc, had very extened treble, with warm mids. Look forward to hearing your thoughts, after burn in.

I have or had Valvo Hamburg, Heerlen Holland, or Mitcham, UK. Theres a change code on the glass (acid etching) 7L6 for example. Under that is the factory code/year, month.
Germany is D, Mullard R or B, Holland a right triangle.

I have a pair of Valvo Hamburg E88CC - A Frame disc getter - not sure if they're 1956 or 1966 but haven't listened to them in a while - they were once one of my favored tubes, but dont remember the characteristics. I'll put them in and see what they are like. Etched codes on mine are 7L - D6J1 - I know the 6 is year but not sure if it's 50s or 60s (would guess 60s)

66 I believe.

I will check the code once I go back to home.

66 I believe.

I would think so too, with the a frame. I have a pair of siemens a frames, from 1970, that I got from Upscale Audio.

56 would be pinched waist as well. Hamburg PW are rarer than the Holland and USA.

Just pick this up. Not bad price.

I am new to the tube world...just a question
Isn't LC designed for 6DJ8 tube configuration. Can we use 12AU7 tube in it.
Also is there any benefit of using 12AU7 as compared to 6DJ8

At the risk of re-posting information from the LP thread, I thought it would be worthwhile to get this posted again in the LP tube rolling thread. The following are some of the tubes that I have rolled in the Platinum and my top choice of each tube type.
2C51/396A/5270 - These work well with the proper adapter. My pick - 50s Foton triple mica
12AU7/ECC82 - These also work well with the proper adapter. My pick - 62 Telefunken Smooth Plate
12AT7/ECC81/6201 - These did not work for me - very audible noise - I tried a variety with differing degrees of noise. Requires adapter and assume the noise problem is related to tube amp factor. 12AT7 amp fact - 66 where 6922 amp factor is 33 and 12AU7 is 16. Based on this I assume the 12AX7 would also not work with an amp factor of 100. I look forward to others trying these to confirm my findings or not. My all time favorite tube pair are 50s Valvo PW 6201s.
I've tried quite a few 6922 and variants which I really like, but the the best sounding tube pair, by far, that I've tried in the Platinum are late 50s Sylvania 6922 D getters. They are rare and very hard to find and I can only hope to come across another pair.
So, that's a start - I have more tubes to roll

Despite several days of looking for similar testing Mitcham ECC82 singles, I went ahead and bought this set. A bit pricey but not terribly expensive.

Have you had good results, with that seller on ebay? He or she seems to always have good ones.
