Be careful with this ebay seller. I bought a pair of Mullard 6SN7GT that originally he said that they were coded like that because they were made for the USA market. Blackmore identified them as not Mullard but Tungsram so after questioning him he admitted they were Tungsram made for Mullard. What I really believe they were actually Tungsram re-branded by himself as Mullard. I was able to return them and get a full refund. I would make a lot of specific questions before buying any of these Brimar. One thing strange is that the lettering looks very new just like those Mullard I bought.

It was lucky Blackmore knew about the real tube, otherwise it would have been a disaster.

Does anybody have any info about the Mullard ECC33 Black Base with Yellow Print?

Can you post or link to a picture?  There are some of those that are really Russian tubes.

I believe they are original Mullard circa 1963-1964.
They used yellow paint for a couple of years.

Those are definitely real. You can tell by the plates. I have never heard them, though.

They test extremely strong with very well balanced sections.
Sound check to follow, hope they sound as good as they test.

You lucky dog! Where did you find them? I have been looking for real Mullards (ECC33 or ECC32) for long time with no luck.

Here is a pic of a ECC32 with Gap Getter currently under test on one of my SP Extremes.

One of my sellers is US based but I can't recommend him as I currently have a dispute with him.
I also use an Ex Mullard electronics engineer who unfortunately has some health issues right now.
Otherwise they occasionally turn up on ebay.

You'd be surprised how many tubes can be found in old photography stores. Yes sounds strange but I have seen a box full of them a few years ago in a 2nd hand photography shop. Worth a check if you have one near you.

Has anybody tried the 33S30B?
How does it compare to the RCA 5692?

I have heard good things about those, but never actually heard, or even seen, a pair, myself...

Well it's giving the Mullards a hard time!
