Lampizator Level 7

Thanks Norman swapped out whatever Lukasz supplied for a Sylvannia kindly donated to me. Haven't pulled out the ECC40's but take it they are Mullards?
Where did you get the Tungsram valves? Are there various Tungsram styles or is whatever one I find squat construction
Are these the ones? http://www.ebay.ie/itm/Tungsram-ECC4...-/390690968369

or these http://pmcomponentsnos.co.uk/Tungsram-ECC40 Same shop different price

Yes, That is the Tungsram I was talking about.

I never saw Tungsol metal base before. Need to start looking. For the RCA/Sylvania ceramic bases are their base in white color? I have some RCA/Sylvania ones but the base is not in white ceramic color. I'll need to try those sometimes.

I am not certain but I suspect the L7 is cathode-biased so the bias will stabilize itself. I'm not sure what 'wattage' is referring to. Is it the filament wattage or plate dissipation?

Sorry, my bad. Black or brown base, not white base.

TSol metal base is verrrry hard to find. I have never seen it, but the yanks have gone out of their way to vouch for the quality…From a practical point of view, just try fro black/brown base RCA/Syl. 6x5.

[wisnon]

Yes they are the ones I have.

Singularly stupid pin out on them though, which makes it hard to line up in the Lampi. Make very sure the nipple in the glass lines up with the red marker Lucasz or someone will have put on the valve base. It is perfectly possible to put it in the wrong way.

Yes, just use an indelible marker to line up the nipple correctly with the mark made on the socket.

The underside mounting was to allow tube rolls without opening the case and to allow the component to be stacked in a normal audio rack.

The correct base for a ecc40 prevents incorrect lineup.

I have rolled a bunch of tubes. 6a3 of any brand are very good . the tonsil as some regard as really good are but in truth I prefer the Sylvania and relabled Sylvania's over it. the green writing or green leaf are very good. if looking for new the Sophia princess blacks are also very good. thevt52 are ok but lack a bit. the psvane 101d metal is nice but thin in comparison to the 6a3. I do feel the rolling is fantastic to allow us to tailor our systems to get the sound we crave and cheap . doing the rolling in the dac is better than in cables and the change is massive in some cases.
I wish I could write much more of what I hear but lack the time to do so .
rolling a lampi is the most fun I have had in audio in a long time. roll on people.

Al have you tried 6B4Gs with an adaptor yet? If so what did you think?

Anyone with a pair of ELROG 300Bs is most welcome here. Just state which bottle of expensive wine you require before you show up

Looks rare and NOS but capable of using the nipple. Most ECC40 sockets on ebay have no such provision. Good find Nick.

This plugs into the valve and the socket on the LZ? is there space i.e. will it end up pushing the valve to high and it ends up protruding from the base? (Should turn mind upside down to check first!!) Where did you locate this socket Nick?

I have some somewhere, the ecc40 is a nice sounding valves used it for a number of things. This chap seems to have a few.

Nick that is chassis mounting it would need to be doctored to work on LZ.
