--- Quote from: TERRA Operative on July 02, 2022, 06:03:11 pm ---I've decided it's time to build something to use some of my test equipment on. A tube amp it is... :P It's been sitting here in parts for a couple years now (well a bit more than a couple...) and is going to be a 35W + 35W Push-Pull stereo amp using 4x 7591 'Beam-Power Pentode' tubes for amplification, and some 6AN8 tubes for the pre-amp stage. It's taken and modified slightly from the March 1961 'Electronics World' magazine. So far I'm drilling holes in the chassis, so not much to see yet. --- End quote --- WOW !! Didn't know you were into vintage stuff, you took me by surprise !!! :scared: I hope the finished product will look better than the 3D rendering... the colours are a bit awkward ! :-DD Looks like there is only a volume control, no control for left / right balance ? Could be useful... 6AN8 LIKE ! I mean....it's used in my Tek type 502A scope, 7 of them in there no less ! So I could do with spares, send me some ! :-DD |

I love old glowing glass ;D , I got a collection of CRT's including a Maltese Cross Crookes tube and a 'Beam Bend' experiment CRT that has a phosphor panel along the path of the electrons so you can see a line and bend it with magnets. Even got a HeNe laser tube here somewhere (I used to have 5-10mW ones when I was younger, pulled from old tabletop-mounted barcode scanners you used to see in the shops). I don't often use balance controls, I like to set up the room properly instead. My living room has a decent layout, so not a problem. I plan to eventually get a reel-to-reel tape player to hook up to this amp too, but that's a future project.... I also have a bunch of parts to make a tube based PSU, good for a couple hundred volts or more. One day I'll get to building that too. |

Does anyone actually use the POI lists to find stuff in this thread? ??? --- End quote --- Yes, I use the POI sometimes. Thanks for maintaining it :-+ --- End quote --- Certainly. BU508A has been catching new equipment that shows up so I can add them. :-+ I'm tossing around some ideas in the back of my head regarding how to keep it growing. It's gotten pretty large, affecting its usability. |
