Altec 1566A

Tomorrow I am going to start building an Altec 1566A.  I got the schematic form here.  I scored input and output transformers at APEX today hope they are the right values. They are made by Tetrad Co. Inc.

Input is a LEAR#91881  T 102
Output is a LEAR#91934 T 106
If anyone has anymore information on these transformers that would be great!

Ill keep the blog updated on progress. Also anyone want to start a Hacker/Maker space in Huntington Beach with me?

Tube Powered Flash-drive

I came across an image of a vacuum tube with a flash drive sticking out of it tonight and I thought to my self well my flash drive is stupid looking in its plastic black case so here it is. After breaking it out of its black case I realized that the flash drive its self is really small and would fit right over the pins of the tube so its just wedged onto the pins. Works great!

Reboxing

I built this pedal originally about a year or so ago now its two Zvex SHO in series with an in and out loop for each stage and well as volume control for each stage. When I orginally built this pedal I was off in some of my measurments so the loop functionality did not work do to the output jacks touching together. I wanted to try fix this problem as well as try out Frequency Central Layout that adds an additional 2N5457 into the circuit which gives an extra crunchy tone. While cleaning out some of my parts I found this extra enclosure that I had so I figured that now was the time to try it out. Still working on it currently but here are some pictures.

Laying out the box for parts:

Adding pots and switches to make sure everything fits and allow for easier soldering:

New circuit form Frequency Cental at the top in the center:

555+4040 = Fun on a rainy day

Nothing much to do today school it finally over and I got some more time to mess around in the garage. Nothing to fancy here just a 555 acting as a clock for a 4040 and having a grand old time. The signal is pulsing because the power rail is coming in contact with one of the outputs of the 4040.

Faces of Fuzz

Big Muff Triangle

This is a EHX Big Muff Triangle that I have been working on today; Its based on the layout by IvIark 

 

T.L.B.

Just another update of the Tube Loop Boost; Its all wired up and works properly but not perfectly, Ill need to do some tweaking to get it working 100%. Well enough chit chat here are some pictures. 

Tube Boost Looper

This is for a project that I am currently working on right now. Its a dual tube boost with a FX loop.  Its based on the Bass Paralooper  and the Valve Caster . I have two identical boosts, modified with larger input capacitors; Currently I am just using the trim pot to set the gain. More to come later!

Update:

So I drilled out the case yesterday but screwed up on the placement of the jacks for the loop send and return, they are in the way for the tube sockets.  I think I'll take a brass strip and use that to cover up the existing hole and mount the jacks to that.  Other than that screw up this is one of my most accurate drillings for an fx box.  

 

Mammoth 2

This is yet another attempt at the Mammoth Fuzz I could not get the other to sound like I wanted it to so this one will work hopefully.  Same layout as before from Tag Board Effects Used a Dermal tool to grind the Copper away leaving nice pads to solder onto. Build time was about an hour and half.

Please leave a comment telling me what you think.
