| This just came in yesterday. Thought I'd share my peek inside. LaChapell 583s Tube Preamp for 500 series racks, complete with Telefunken tube. ![]() ![]() Opening in the top of the unit for swapping tubes (seen below). ![]() NOTE: I don't understand why these images aren't showing up in the body of this post. I put HTML image tags around them. Oh well. If a moderator could edit this and make them show up, I'd appreciate it.

| Sure, they're 4-gang 16mm film synchronizers. And a squawk box on the floor.

If the image resides on a server already though, you can just add image tags to its URL and it should show up in the post. Like this: LaChapell 583s-On the inside - 3dB For some reason, this thread won't allow a post with image tags, at least not from me. | |

| I don't know if you are a great collector, or a pack rat. I love those old racks and heavy steel chasis. -tINY |

| Gearslutz.com admin | OK I tweaked the IMG code option, (I dunno why it was on the off position.. )Try now Lynn! Pan 60, with a big forum you get a lot of attachments and a long term solution needed to be put in place. Thats why you have the thumbnails, at least it shrinks the photos for you..

Thanks. but i had to post a new, edited photo of Ken Kesey's bus on every post I made April fool's day - instead of embedding an image of the same one... Here is some vintage gear (look on his head) ![]() -tINY | |

| Nice! Are 9-pin sockets current Chinese production? Can you share design of PCBs for tube sockets? |

| Fender Bassman: the classic, and the reissue I recently did a head transfer/cabinet swap. Here's a view of original-versus-reissue shots of the Fender Bassman. The only "new" components in the classic 54-ish Bassman are two electrolytics. You can see the reissues' PCB and such. Both the owner and I think the original Bassman sounds better than the reissue. I put the original head unit into the reissues cabinet, because the old cab is literally falling apart, and had some major resonance/vibration problems. Even with the new cab and reissue Jensens, the old head still sounds better.

| Lives for gear | I would put a grounded AC cord on the old one to keep someone from getting the crap shocked out of them... |

| I'll pass that on, would it require a great deal of modification? You know the owner, btw. |

| Lives for gear | No mods at all, the only problem for the guy with no or minimum tools maybe the problem of the new cable requiring a grommet and strain relief. I never reuse the old plastic grommet Performed this upgrade this past weekend on an old Ampeg head. The ground wire connects to the chassis, the black/hot connects to the switch/fuse leg, white/neutral connects to the power transformer. If it contains the ground switch like the Ampeg did you disconnect it completely.. Leave the switch in the hole or cover it, your choice. |

| Thanks Mike. The ground switch is there, and the plug is 2 prong. The consequence to switching to 3 prong is the elimination of the ground lift switch then? What would opening the neutral wire do in the 3 prong scheme? Put the 120 across that open? If the neutral wire is already connected to the chassis, would I need to find it and disconnect it also to implement the 3 prong scheme? I ask because we've been fond of using the ground switch to eliminate/reduce hum with guitars. I'm sure my ignorance is showing on this one, but I'm kinda playing on-site studio tech. I've read that in three prong modern systems, the neutral wire is connected to earth back at the main breaker terminal, so I guess that a neutral short to chassis, the neutral being shorted to earth ground at the main breaker, would create a ground loop between the neutral/chassis and ground, and possibly in the operator touching the chassis and standing on earth ground. |

| Lives for gear | It is not a ground lift in the real use of the word. Lifting the AC ground on a tube amp is a very bad idea, you lift the audio ground different ways. I would always prefer the AC ground to be connected if possible... But it is NOT allowed by NEC to use the neutral as a ground, yes it is connected at the main panel at one point and ONLY at one point, either at the meter panel or the main disconnect, but not at both and no where else. This creates a parallel neutral current path, a bad idea. NEC 250. |
