Here is my finished amp (for now). So many people to thank- mainly Eli Duttman, Jim McShane, Captn Dave, TheGimp & others. All tubes were replaced including Rectifier. Filter cap replaced, Nichicon axial used for cathode bypass. IC MPW PP caps & Panasonic NOS PP film/foil caps were used. All resistors more than 5% out of tolerance were replaced. 3 wire power cord with 3A SB fuse, & LED were also installed. Enjoying this 50 Yr old Magnavox rebuild with my Klipsch Chorus II's......AWESOME!!

Hi,

The connections use 7 pin iec plugs and sockets bought from ebay. (Only four connections are used in this application.) They are rated 250vac 10amps but I rang the UK importer's technical department and was unofficially told that they should be able to handle 400-500vdc. The B+ is about 300vdc so I think safe enough...

This is the matching preamp to my 2a3 amp on page 404 of this thread. The layout (inspired by the Icon Audio PS) was my solution to be able to get both on the same shelf. Thanks

Default Headphone amp

Not finished (transformer needs a cover and I can't make up my mind about a few other minor details) but almost there. To be honest it looks like a DIY amp (it looks crap) but it will do. It was supposed to be a Mu follower + Cathode follower but when I started wiring it I got lazy and it ended up being only a SRPP stage. My headphones have a high impedance (600 ohms) so I think it will work, if not, I have two extra tubes to fix any deficiency. I'm not a headphones fan anyway.

Sometimes I build stuff that I don't need. Looking at the positive side, it is true that later I enjoy destroying stuff that I don't need. Kind of a mini god in my own terms. Anyhow, none of my creatures is perfect - they must die sooner or later.

Unfortunately, my shortcut (SRPP) has failed miserably in its task and now I'm back to the original plan. Last picture.
