    Here's my layout (found it on someone else's photobucket :lol:):

    [​IMG]

    Well, the board, anyway. The grounding and tube socket wiring are as Mr Ridesglide said - just like the 5E3.

    The exception is the 6AT6/6AV6 in the first stage:

    [​IMG]

    The original 5F10 drawings have pin 4 straight to ground, but I wired it with one heater tap to pin 4 and one to pin 3.

    I'm so glad the ol' tech docs are still out there, too:

    Thanks, I have that layout. [​IMG]

    I've done a 5E3, a 6G2, a AB763 Deluxe Reverb and a 50Watt Plexi lead.

    I have a 5C8 in the planning stages but I always wanted to try a 5F10.

    I nearly always make some changes to the standard layout, but if someone else has done the hard work. [​IMG]



    Thanks.

    If that pic doesn't print actual size, I can get you the PDF that will so you can use it as a drilling template.

    Not quite to size, but I'll re-draw it in AutoCAD.

    Thanks again.

    I've got a PDF that I made in vector graphics that's to size. Just PM me and I can e-mail it to you.

    Glad to see this thread revived. I've been delayed, but in the midst of a similar build with same layout.

    I'm doing another one. :lol: The original one in this thread was sold a couple years ago.

    This new one's in Brown/Wheat:

    And now we wait...I have some components on the way! Hopefully just prior to New Year's I'll have the board populated and such.

    Thanks for following along. :D

    Beautiful work MGB. Is that one of Weber's stainless steel chassis or an older one? I ruined a good Greenlee punch on one of those stainless chassis, they are tough to drill or punch.

    I'm thinking it is a steel one. Had some serious issues with my step-bit. I liked the older chassis better for sure.

    A little more progress this holiday weekend.

    Nothing like some heater wiring:

    And a start on the power tubes:

    There are some more parts on order and should arrive next week. Will update y'all then!

    That is a beautiful build. Solid core wire looks so much better than stranded.

    I look forward to seeing all the awesome progression!

    Btw, for anyone who want to build this amp. The only PT I found that matches the correct specs of this build for export is the Hammond 270CAX.

    Check it out.

    I use Allen's Heyboer TP25 for mine - for those in the US or Canada:

    [​IMG]

    Upgrade Power Transformer for BF/SF Champ™, VibroChamp™, Bronco™, and Princeton™. 310V-0-310V @ 150ma, 6.3V at 4.5A, 5V at 2A. 50V bias tap, center-tapped heater winding and internal hum shield brought out to a lead for grounding. 2" by 2-1/2" mounting centers, 5.1lbs. Unit is approximately 1" taller than a stock transformer. Supports the use of both 6L6 and EL34 power tubes (with proper socket wiring). Now featuring M-6 grain oriented lamination steel for cooler operation.

    It is a little tall, but it drops right in the 5F2A chassis and there's clearance in the cab (but not much).

    Just waiting on a batch of parts from Antique Electronics now!
