So my favorite tubes currently are the Mullard Mitcham late 50s early 60s.
I bought a quad of Mullards from here
http://www.ebay.com/itm/262287616448 suspecting that they are indeed the early version from the picture (wrinkle glass / milky ring on top ) and I got two tubes that were from the 1950 and two that were from the late 1960s. So it's a bit of a gamble. But I am currently running the 50s ones full time since I got them in August. They did not test amazingly strong on Ia but had decent Gm.
It's a bit of a gamble... but I am pondering another quad purchase
Funny thing is I have written a message a few months ago asking langrex if these tubes are from the 50s or 60s and they told me they were from the 70s, after getting them however there is no doubt they are late 50s and early 60s.
My replacement of shorted WE JW 396A pairing very well with original survived tube. On my DAC I using right now Tung-Sol 2C51 and on my MJ2 WE JW. This combination brings best from two worlds: midrange and transparency Thung-Sol with thickness and bass to midrange oriented with exceptional detail retrieved from this frequencies JW.
Anybody here have experience with Heerlens Holand E188CC d-getters ?
No..but I would love to get my hands on them
Same goes for:
1) Siemens E88CC D-Getter
2) Siemens E88CC Disk Getter
3) 1955 Philips Venolanda '+' on the plate E88CCs
4) Lorenz Stuttgart E88CC - 2 and 3 mica
5) Lorenz Stuttgart PCC88 3 - mica
Edit: I've managed to procure a pair of gold pin LM Ericsson 2C51L at 150$ matched pair from Tango Tubes sweden. I have not gotten it yet and have only seen a picture so I will update you guys how it sounds compared to the steel pinned one I already have.
Edit2: I've asked Roland@Tango Tubes if he has more pairs and he said he does - not sure how many but if somebody is hyped up feel free to contact him yourselves ( just google tango tubes sweden).
