I wonder if the seller of those fuses actually gets any sleep at night or if they were just born without a conscience

He sleeps in the back of the limo while he's being driven to the bank.

Only two- where are your backups?

With the bankruptcy trustee.

It took me long to find a pristine pair for a fair price. Coincidence gave me a cherry picked AQ2408. I hope those are rare.


So this would be the reason why I don't have more GECs. Starting to organize my collection right now. Before it was quite hard to find a certain tube.

Looking good! I have to do the same thing soon. I’m at the piles of shipping boxes stage.

Those will hold their value. As long as you don't actually use them Rare antiques - especially a matching pair like that with matching boxes.

What tubes are inside those Los Gatos and Pope boxes? I think both those companies were rebranders. Maybe Philips in the Pope boxes? Fivre in the Los Gatos boxes?

I also keep my tubes in boxes like that. Had to build shelves/cupboards in the garage last summer for a bunch of the boxes. When I was building those shelves I kept telling myself "must not buy any more tubes". I've done quite well since then and only fallen off the wagon a couple of times.

I really had to search for those Los Gatos boxes in the picture haha. Those are Sylvania 6sn7w and vt-231 relabeled in the 70s.

Bingo! Pope was a Mullard/Philips brand. I have a clear and older grey glass pair of those Philips 6sn7gt. Absolutely rare I hope

Yea, I wonder why those are so pricey. They're quite readily available but too expensive to afford. They don't even have that lovely warmish British sound. It's actually a brighter tube.

I’ve had a trying day. Got my metal based b36 to match up with my lone one. Promptly tore off the end of the original Marconi box. Sigh. I have to keep reminding myself that these boxes weren’t designed to be any more durable than cereal boxes really. I’ve had to throw out so many that have self destructed.

Anyway, time to pair it up with my existing tube. Except I can’t find it… Grrr…. It’s around here somewhere but I haven’t used it in over a year or more so it will take some digging. Speaking of digging, brought out one of my b36 tubes that I never opened before. Original box and everything, wait, what’s that? Made in Holland? Groan…

Black base and fully blacked out tube. This doesn’t look like any other “Marconi” b36 I have seen. Any idea what this actually is? Is it Russian? I thought this was going to be another red/brown base b36. Actually I was counting on it so that it would be a match(ish) to one of my others. Now it looks like I have another pair of orphans. I’ll definitely get another red base, dunno about this one. Getting a matching twin will depend on what people think this actually is and if it’s worth getting.

In happier news I have rediscovered the 13d1. I had a great experience with it a year or so ago but when I tried them after that they always sounded flat and dry. Same thing happened earlier this week. I then realized 2 things: this was probably a different pair than I had been using before and other highly regarded tubes have also sounded that way until I let them burn in. So I let them burn in.

Took a good 8-10 hours for the dryness to go away but they are now singing along quite nicely. Slightly forward mids but well balanced and detailed overall. As compared to the 14n7 that I had in before they sound a bit smoother and don’t quite have that Sylvania bass but still a great sounding tube when used with the Sylvania 6bg6ga.

I have one 'Marconi' EL41 made by Philips in Sittard, Holland for Marconiphone CO. LTD in Great Britain (B. B. = Before Brexit). They are branded MEL41. I also have one MAZ 41 'Marconi' rectifier with factory code 1m HD1. AZ1 November 1949, Eindhoven
Are there any codes on the bottom around the pins?
