Yep...I'm using Spendor LS3/5A speakers in my office, powered by a Marantz 2285 and fed by a Vincent Audio tube DAC...like I said...I can't really talk biggrin.gif

Very nice set up indeed, I like the cart idea.

 

I hope you got some help!

 

I am exercising hard lifting Easter Eggs!!!!!!

No new cables. Although if I were to get any they would be no longer than 3 feet. I'd get them shorter if possible. The cart setup is just to roll amps (literally and figuratively!). I'll roll the cart into the living room where I would connect the speaker cables and others to the amp on the cart and then listen to it. Then when I'm done I'd just disconnect the cables and roll the cart back into my bedroom. Theoretically that is what I'd like to do. I have yet to practice that though.

Who needs dumb bell curls when you're moving amps around.

Still hooked on The Army of Lovers and  FIVRE 6CG7.

Stavros, how is the 6cg7 and 6sn7 Fivre? sound wise.
post #2485 of 10867

The 6CG7 is not as detailed and nice sounding as the 6SN7.

 

I am testing a pair of FIVRE 6SN7 Black Plates I got a few months ago for EUR4.90 (yes it' true!) when the ebay God was asleep.

They have the rare black plates and one is missing the spigot but still testing strong and great sounding.

Unshielding the German Post C3g

 

It's doable it turns out.  I received my initial order purchased off eBay today.  As it turns out there is not much risk to the tube doing this.  The glass tapers in slightly towards the bottom of the tube, so you are not actually putting much pressure on the glass when prying the two parts of the casing apart. 

 

What it is, though, is a pain in the ass all around.  The base and the top part are stamped very closely together, much like a soup can only with a much finer bottom edge.  I was able to produce two naked C3g tubes after a considerable amount of toiling and a LOT of visible nicks and scratches left on the base part that needs to be re-glued back onto the tube.  Well, technically you don't need to but without it you have no guide pin and that just seems like a recipe for disaster to me.

 

I used a small pocket knife because the flathead screwdriver suggested by Jac doesn't have a fine enough edge to peel back the initial layers and get you started.  Only slightly stabbed myself once, not a bad showing all in all.  tongue_smile.gif  The other hairy part is that it is hard to get the initial opening pried without pressing against one of the tube's pins due to lack of clearance but some care is all that should be necessary to prevent bad things happening there.

 

The tube looks pretty neat in the bare glass, typical pentode businses but better made and with open frames and gold grid posts.  It doesn't have the wire mesh the C3m but its still a million times nicer than looking at a painted black can.

 

I would say the most pressing question in my mind now about the C3g in general is:  do the various makes have different sounds much like different makes of 6SN7 do?  The Siemens seem to be the cheapest simply because they made the most of them, but there is also Telefunken, Lorenz/ITT, and Valvo all of which cost more money.  Are they more expensive just because they are more rare or perhaps one offers better sonics?  A question for another time.

Can we get a picture please? I left my C3G untouched for now

I don't think the Yamamoto sockets you want to use even have the center pin connection that gets grounded.

It is better to remove the shield then have it not grounded.

 

It looks like you will have to try all the different makes after your amp is built!!

Glue is drying right now, so maybe a little later.

Actually these sockets do have the electrical connection for the center pin, I asked Jac this question.  My fear was what if the locking part of the socket was stronger than the glue I put on the base and the tube came out with the base still stuck in the socket....?  Jac suggested a two-part epoxy but that stuff is so messy so I used Loctite control gel and will just have to hope it wasn't a mistake on my part.  I suppose two pairs of pliers would get that base piece out if it did happen, afterall the socket is screwed into the chassis so it certainly isn't going anywhere.

 

I got impatient and bent a pin doing the 4th and final tube but I think I managed to save it.  After some pin polishing and Deoxit treatment this evening they'll be ready to go.

 

I'm trying hard to convince myself all these tubes will sound the same, the Telefunkens go for $200 a piece just doesn't seem like a big deal since Clayton thinks the Siemens sound really good already.  Maybe after some time has passed I'll throw money at one of the other brand types to satisfy curiosity but not right out of the gate.
