    So I have this Swart STR Tweed which I love but the Quarantine hit and the whole family is at home All day long going stir crazy and NOT liking it when I crank up my Amp and play. Even with being a 6 watt amp, it is still really loud :)

    So, in order to keep peace in La Casa, I got the idea to build a low wattage Bedroom/Den Tube practice amp. It would give me something Fun to do for awhile.

    Researching 1 watt Tube Amps I discovered the Boot Hill Six Shooter. Being a “need for Tweed” guy for many years I contacted Dave at Boot Hill and asked if his kit could be installed in a 5F1 Champ Chassis. With a little customizing, Dave put together a Turret Board and all the parts in Kit form for me so I pulled the trigger (pun intended).

    I’ve never built an amp before, but I have always done my own guitar wiring, fixed broken pedals, etc. So as I waited for parts to arrive, I started reading through the Build Threads, studying and learning from what others have done. I’m in no hurry - it’s kind of a learning and therapy project for me.

    I’ll share as I go and welcome the input and advice of the guys who frequent this Forum...

    I received the Six Shooter Kit and it was all I hoped it would be. All parts labeled and accounted for. Clear Layout and Schematic information. Really nice Kit.

    I had planned on working on the Chassis hardware first, but realized that the leap/bulb/jewel assembly would not allow me to change the Color of the jewel. Not a big deal to most folks, but I have developed over the years a fondness for an Amber Jewel for all my Tweed Amps. OCD, I know... sorry, lol. So, I resourced and ordered a Fender Amp bulb assembly (I already have extra Amber Jewels). Since the twisted heater wires are attach to the lamp assembly, I went ahead and stalled the AC Cable, Transformers, and Fuse post and set the chassis aside. I also went ahead and made some heater “twisted pair” like I learned from Dave’s YouTube Tutorial.

    Go slow, have fun, enjoy the ride, then prepare for amp build #2!

    Here is the Power Transformer, AC cord and Fuse installed. On one of the builds I studied here someone had suggested insulating the exposed Fuse lug, so I heat shrunk it...

    Also read here to crimp AND solder any ground lugs. Good advise!

    With the Chassis set aside waiting for parts I started on the Turret Board...

    Installed turret board in chassis along with the pre-wired Switch and input jacks.

    Everything is wired up except the Output Transformer leads. I think I read somewhere there is something you have to do first. Does anybody know?

    I’ll do some research.

    Are your heater wires correct? I am not use to seeing pin4 and pin5 taking each heater wire.

    I think so but I will double check! The heaters from the lamp go to 4 and 5 on the power tube, then proceed to the preamp tube, right?

    Wait. I may be wrong depending on which tubes you will be using.

    Since you have the artificial center tap (the two 100ohm resistors from the lamp), I am sure you want to change the heater supply to the typical 6.3V design.

    To do so pin4 and pin5 of each tube are connected together and receive one of the heater wires. Pin9 receives the other heater wire.

    The heaters from the lamp go to pin4/5 and pin 9 on the power tube, then proceed to pin4/5 and pin 9 on the preamp tube.

    This will be the quietest method reducing hum.

    My bad.
    With the 6J6 pin3 and pin4 is correct.
    With the 6cl6 pin4 and pin5 is correct.

    Never mind the previous observation.:oops:

    Carry on.

    Hey, no problem my friend! Thank you so much for checking in and looking it over for me. It’s my first build, and I am learning as I go.
