OK-- Here's one!

A buddy of mine had this ValveKing 112 that his cat used as a claw sharpening pole. Completely destroyed the Tolex. It had other issues as well I had to fix....

Anyway, my very first attempt at a Tolex job. It came out perfect!

Other issues/fixes:

The reverb did not work. Found a broken "suspension" spring in the tank. Fixed.

Replaced the red jewel and power LED with blue. Of course!

Replaced the tube covers with blue anodized. Of course! (blue is better). Blue snakeskin Tolex too.. groovy cool!

Added a tube bias mod to heat up the power tubes (42mA now)/ 21 Watts! Nice. Also did the "Mesa" boost mod. Nice!

Retubed to: Matched JJ - 6L6GC Power Tubes, Matched Tung-Sol 12AX7 in V1 and V3, JJ 12AT7 in V2.

Great little project and super results! MC

eBay-- Some Chinese Co. (There are many choices).. I think about $10 for 4 including shipping...

If you can't find some, let me know and I will research my past purchases...

Edit-- it was ( 8 ) for $11.50:

Edit/Edit.. the tension springs in the blue Chinese ones are a little cheesey. Pull the springs out of the silver OEM ones your are replacing, and swap them. Just a tip. These add a nice look for just a couple bucks per project...

You can also see the "locking" potentiometer in front of the blue shield. That is now the added output tube bias adjustment...

Hi,
another tiny amplifier!
this one is a vibratone, introduced by Frequency Central here:http://www.diystompboxes.com/smfforum/index.php?topic=83831.0

Nice work, both of you. @Mark: where did you find the blue snake?

italianguy63 · « **Reply #505 on:** December 28, 2014, 06:46:02 AM »

If you are serious about knowing... in the magical land of eBay. I wanted something to go with the "blue" theme.

I don't know why, but I do tend to use a lot of blue-- LEDs, PCBs, hardware, etc... in my work. Maybe my Picaso Blue Period?

I was being a little facetious, but it *does* look cool, and I do have some tolexing to do, so you never know...

deadastronaut · « **Reply #507 on:** December 28, 2014, 10:53:19 AM »

nice work mark...love the blue snakey stuff..

@thomasha , very cute little valve amp..

tca · « **Reply #508 on:** December 28, 2014, 11:47:12 AM »

Too small for me, but very cute.

What's the speaker? Full range?

Cheers.

thomasha · « **Reply #509 on:** December 28, 2014, 02:21:04 PM »

Thanks guys!

It's a 3" old television speaker, I think it's full range.

I thought of that, it seems to be magnetically shielded! Otherwise that magnetic field would perturb the tubes and the output transformer response.

would perturb

My better 1/2 does that religously.

Here goes a 1x12 cab with a cheap (30eur) 12'' 96dB speaker:

Works great with chimp amps (LM386, PUNCH,...) and other small amps!

The two handles are from IKEA (EKEBODA), it weights 15kg,

makes it easier to carry around.

Cheers.

Hi!
Built another One! now with 30x25x15cm and a Jensen Mod 6 speaker.

It follows the TMC1 amplifier, by DvNator, with an ECl84 and a 12ax7.

Used old wood that was laying around at my grandfathers house. Tried to make a finger joint with a saw...and failed. Had to fill, but it was a learning process!

Well, the faceplate is vox inspired..., the circuit is Trainwreck inspired, and the combo is british inspired...what was I thinking?

For a 1W amp it's to loud to play at night...so I'm here posting pictures!

This circuit was developed by DvNator at the "tone per buck" from Wattkins, pretty nice build!
Cheers, Thomas

Super build Thomas! Classic vintage look to it.

+1. That is just beautiful. Has a very old feel to it.

pickdropper · « **Reply #516 on:** March 23, 2015, 05:15:07 PM »

Here's my 18W build. I didn't build the cabinets, however. My only contribution to the aesthetics was the faceplates

And here's a gutshot of it mostly wired:

stallik · « **Reply #517 on:** March 23, 2015, 05:49:20 PM »

Very very nice

deadastronaut · « **Reply #518 on:** March 24, 2015, 07:40:01 AM »

+1 totally cool...

tca · « **Reply #519 on:** April 03, 2015, 06:12:12 PM »

One more for a 8'' woofer

Cheers.
