Default Scott17 KT88 SE Tube Amp Build Log

Hey all! So I finally made a decision about what amp kit to build for my very first tube amp project! I'm building one of scott17's KT88 SE amp kits! In the build log to follow, I'll be detailing the build process.

Tonight: Reading the manual...
Soundtrack for this evening: Me'Shell Ndegeocello - Plantation Lullabies

The rest of the week may be a bit challenging in terms of making major progress with the amp. I think I'll try to get the major components installed into the chassis (tube sockets, chokes, etc...) so that I may start wiring this weekend!

Looking forward to this thread.

Wow, I have not read that first page in a while. It does read as rather intimidating. I did cover all the bases though, so to speak.

You're going to have fun.

Best of success,

Scott

Alright, entry 2!

Today: Due to a crazy week at school/work, I didn't have time to install all the hardware into the chassis. Thus, today I tackled installing all the components...well MOST of the components.

Soundtrack for the build: The Absolutely Essential 3 CD Collection - Django Rheinhardt (Figure 1)

Ready, get, set... (Figure 2)

And we're off! (Figure 3)

So I installed the hardware as instructed in the EXCELLENT manual (Figure 4), and ensured that the keyholes in the 8 pin tube sockets were facing away from the switch (Figures 5-7).

Then I installed the chokes as instructed (Figure 8)... But... OH NO! One of my chokes has a frayed wire (Figure 9).

Moving past that I installed the RCA jacks (ensuring to install them in the order of the plastic washer, nut, grounding lug, and then the second nut as instructed, Figure 10).

I then installed the binding posts (Figure 11) and the volume pot (Figure 12).

So, I'm stuck at this point. Should I order a replacement choke? Or should I simply heatshrink over the fray? Would that be safe? Before I proceed, I have to figure this out... Hopefully I can start the wiring tomorrow! Unless I have to order another Hammond choke... hmmm...

(Pictures will be posted in the subsequent posts...)

Please send a photo of the frayed section so I can access the situation.

Thanks,

Scott

Just solder that back together and heat shrink it. It will be fine.

It's all looking good by the way. Just take your time and don't rush through the process.

I am just about at the same build level for the same kit. I started on the signal input wires yesterday, and discovered I have misplaced my heat gun in my recent move.

Off to Home Depot for a new heat gun (just could not find my old one) and some black spray paint yesterday, and then the SuperBowl, no further work got done.

My kit has the colored chassis, and bell covers. I plan on painting the transformer sides, and the motor run caps black. Hopefully finish the input cables to the volume control tonight. Will wait a bit and see if the weather warms up before trying to spray paint a couple of nights in a row.

Keep up the great blog!
