Delta Sierra

I cannot stop acquiring tubes. Toeing the line between "quirky enthusiast" and "filthy hoarder" here.

Don't know anything about these three, except that they're pulled from old arcade machines. One of the large ones has substantial burn-in but may still be useful for something. The other two look to be in great condition... if I can figure out how to power them and get them a useable video signal.

Do you have transmitter triode tubes?

@fullrange Nope, my collection is mostly CRTs and Nixie tubes, plus one lonely Aerolux gas discharge tube

good luck in finding Rodan CD47 😁👍🏻

@fullrange I'll admit I hadn't heard of that one, but HOLY COW. It's MASSIVE!

@notthatdelta oo i wonder what cabs they were in

@kirakira me too! I'm hoping to start pulling and researching model numbers tomorrow, weather allowing (I have to move them from the garage to my workshop still).

Although I'm sure the tube model numbers will just tell me a range of cabinets they might have come in. Might be able to read the one with the burn in though.

@notthatdelta @kirakira I can maybe help here; the tubes might have model number labels on them, but they'll just be for the tubes. The chassis may or may not have part numbers printed on them, doesn't hurt to pop 'em into a search engine, but arcade monitors are often identified by sight. Like, a Wells-Gardner K7000 series monitor won't have "K7000" written on it anywhere. An Electrohome G07 (Canadian 19" monitor very common in 80's games) will have G07 printed on it though if I remember right. Specific games were unlikely to be matched to specific monitors outside of very specific circumstances. In short it's a bit of an adventure! 😁 These were likely from 90's cabs, your Teenage Mutant Kombat Simpsons and the like, and I'm very curious about the burn-in, there'll always be someone nerdy enough to identify a game by the ghost it left behind

@ifixcoinops @kirakira Thanks again for the great info!

So it was bothering me and I went out to the garage and angled the tube with burn-in around so I could read/photograph it.

It's Xevious!

The other two will remain a mystery, for now.

@notthatdelta One of them looks like one of the K7000 variants. They've gotta be powered through an isolation transformer, or you'll blow stuff up on the primary side.

@ifixcoinops thank you for the advice! I'm going to do a DEEP dig before I even think about applying power to any of these.

I'm too used to CRT TVs and monitors these days (just provide power and video and you're up and running). Haven't touched arcade hardware in about 20 years, so I'll definitely need to (re)learn a LOT.
