Happy Friday my tube rolling buddies! I just scored a pair of 59' Siemens ECC88 from my favorite ebay seller, and can't wait to hear them, and see how they compare, to the Bugle Boy D - Getter ECC88. I am really digging the prices on the 6dj8/ECC88, and they sound killer too. Anyone have any other 6dj8/ecc88 tubes, they like?

You know you were a tube addict when:

- You just found a package from russia labeled "Repair Kit" from March 2018 inside of which are two pairs of 1966 6N3P Fotons rofl. I never got into the entire Foton hype but I remember wanting to and even ordering these tubes, but I guess at the time I just put them on my boxes pile for unknown reasons. The only reason I found them is as I decided to clean up my boxes pile again hahah.

Yup. '50's Telefunkens. Pricey though.

I've always preferred a *good* 6DJ8 to a 6922. And even a 7308. But I'm weird. :grimacing:

Got those on my list, but the 50's, are non existent, at the moment.

I have questions about vacuum tubes and thinking this is the right place to ask.

It is somebody here, who have experience when tubes "are going"? What symptoms I can expected before they die? Can that tubes damage the amplifier?
Depends on the tube type. Most input and driver tubes -- 9 pinners (like 6922's, 12A*7's, etc) and small octals (6SN7, etc) usually just start to sound dull and lifeless and lose dynamics as the cathode emission declines. Unless one of these type tubes develops a short (which would be very rare just from usage or emission decline), it is unlikely any damage would occur to the component they're plugged into.

Alright, that's it. You've gone too far this time. I'm boxing up all my Fotons today and they'll be on your front porch next Wednesday. :stuck_out_tongue:

Ok but you should suspect a high failure rate, and the tubes you receive back will have all identifying markings removed and the insides will resemble GE tubes for some crazy reason.

Wait....that only works with @Ripper2860 . :stuck_out_tongue:

This is my project for today. The socket is a NOS loctal that was made for marine use -- fully ceramic with pure silver contacts. The base is also ceramic with direct gold plate on copper pins. I'll wire it up with 20 gauge Neotech OFC copper wire. The base has a larger diameter than the usuals from China, but does fit through the Lyr's top hole....barely. Will it make a difference sonically with a Frankie? Of course it might. :smiley: One thing for sure is that socket grips the pins of a 7N7 with a death grip. Now if I can just remember which pin on the base goes to which pin on the socket, there's a very good chance I won't blow up my Lyr....

Very nice, I have built several loctal sockets and some of the jacks are terrible, the tubes do not stay in if you can get them to insert at all. These were mostly Chinese made junk so it is nice to see decent sockets out there.

This one was one-of-a-kind I picked up on Ebay and probably paid too much for it. There are still NOS Cinch and Amphenols that pop up occasionally, and both are great loctal sockets. Not necessarily cheap, but usually not stupidly priced either. Usually. :slight_smile:

$30.65 standard shipping is very reasonable.
