6J1 Tube Amp Case update

-
With a positive response to the design over the last week, I decided to purchase the other model of the 6J1 preamp to build for a friend while providing the opportunity to ensure it would fit smoothly in my case. 


Everything looks the same though this model seems a but scaled back with 35v caps over my firsts 50v.


Side by side, I believe the blue board wasn't cut to size as it has an additional 1/4 (give or take) on the PCB, but regardless these boards are physically similar.

Unfortunately the new board didnt come with the brass standouts as included in the last package, so I designed a standoff tray that can be printed. 



The tray works as expected and prints in a short amount of time.

Below is a complete run of parts totaling approximately 26 hours at .2 layer height.



Until I am able to finally get my Lowrider CNC up and running, I have found printing the dfx to scale makes a perfect stencil to achieve more accurate layout of the plexy glass.




Following through the rough draft of the instructions so far, I was able to quickly assembly the second one. 

Hoping to finish up the work this week by cleaning up some files and sharing on Thinkinverse.

6j1 Tube Preamp

I was browsing online for a soldering project for my oldest son for Christmas, when I came across this 6J1 Tube Preamp kit. It is intended for RCA, but I was hoping to play with adding 1/4" jacks to run my guitar through it. What is a preamp?  A preamp is an electrical device that takes a weak signal and amplifies it, making a weak signal stronger for further processing. Tube amps have always been said to have a warmer sound over solid-state. The Build The kit comes with all the pieces tossed in a bag with no schematic, however; the board is clearly marked and all you really need to do is sort it all and organize your components. You can use a page like All About Circuit's resistor calculator  to determine the Ohms by colour code bands, or you can switch your multimeter to Ohms and test manually - which is typically quicker. https://www.allaboutcircuits.com/tools/resistor-color-code-calculator/   Note: The board lists the 2.2k and 4.7k as "2k2" and "4k7"  I

During an installation attempt of an application, a common indicator of remanence left behind of a failed installation attempt can be identified as follows: This error often occurs when a previous installation attempt has failed or has failed to unregister files. More information can be found here: https://docs.microsoft.com/en-us/troubleshoot/windows-server/application-management/msi-installation-error-1603 Resolving this issue usually entails removing registry entries associated with the installer, which can be done painfully searching the registry and manually removing any assosiciations and uninstall entries or using a tool such as MSIZap. Prerequisites: MSIZap Product code MSIZap is part of the Windows SDK, and can be a useful part of anyone's tool kit. In order to make use of MSIZap in a targeted fashion, we need to have the product code we are wanting to completely remove from the registry. Once obtaining MSIZap, we can execute it through the command prompt or browse to it v

PowerShell - Project Final

PowerShell Project The print spooler is a service application that manages printer jobs sent from a computer to printer or print server, allowing for a buffer - though more commonly known as a queue. The print queue as described, is a queue of stored printing tasks that execute in chronological order, allowing for fair use and management of printer resources. While there are various reasons a host may receive errors pertaining to print spooler communication, I decided to write a PowerShell script to run a series of commonly used administrative tasks that simply restarts the service as quick fix script, to meet slightly exceed the expectations of the project as it is a common adminstrative task. To perform this task using the Windows GUI, an Administrator could: Windows Key + R and type  services.msc Once ran will bring up the Services dialog as seen below. At this point we look for “Print Spooler”, right click where we can then stop start or restart the service.
