    Well since I am self isolating at home I might as well build an amp. I have a bunch of spare parts laying around so I think I will make a Deluxe head. 20200319_211205.jpg

    That's a very stripped down, basic 5E3 circuit! Perhaps consider a micro layout. I like the use of the new Bluetooth components. Let us know how they sound! LOL. - Kidding of course. Enjoy the build. The 5E3 is indeed an awesome choice.

    So self isolation dilemma for today, since I have no way to get any electronic parts for the foreseeable future o am trying to make do with what I have. While I have every size of 1/2watt resistor known to man I do not have a single 250 ohm 5 watt. I have 200 and 300 ohm. The power transformer i was planning on using is a MM FBDP, that list a B+ voltage of 340V. Any suggestions? 20200321_121651.jpg

    I'd use either a 200 ohm or a 300 ohm if that was all I had.

    :D :D :D

    Seriously, go with 200 ohms. Biased hot sounds better than biased cold.

    I'm leaning towards putting the 300in and waiting to see what kind of bias I end up with

    I used a 300 ohm in mine- it helped since it ran pretty hot with the 250, so the 300 was what I went with. Been working great for 5 years.

    Well the board is done, had to get creative with my resistor/capacitor choice, we'll see how it sounds in the end. 20200321_165729.jpg

    Parallel a 300R with a 1K5 = 250R

    Equal value resistors in parallel or in series double their wattage rating.

    The 300R will handle most of the load. The 1k5 would not have to be 5watt.

    Rounding up parts, I'm going to have to fabricate a chassis for this one. Wish I had an output transformer with multiple output taps, this one is strictly 8ohm. 20200321_173331.jpg

    Man, you really do have a lot of extra pieces lying around!

    Opened up my Deluxe to take some chassis measurements, discharging my filter caps before I go sticking my fingers in there. I want the controls to be on the front of the amp like a Plexi but I would still like to retain the chrome like a tweed. The best bet might be to tig weld a 2" section into a stock 5e3 chassis, and then cut the 5 tube holes in to facilitate mounting the tubes upright 20200322_144808.jpg

    Is that a Weber Sig 12 without the bell cover?

    I'm really liking that slot in the lower panel, although I wouldn't like to be the one who puts the tweed on that panel.

    Good eye that is a Weber Sig12A-S, it seems to be a really good match for a tweed deluxe

    Decided to start building the cabinet today, didn't have any pine to finger joint but I did have some good 3/4 plywood. Now I wait for glue to dry. 20200323_142206.jpg
