Just finished this mod, and it works a treat! Thanks a million for posting this. I had this bag of transistors sitting around and it's still available from Radio Shack: www.radioshack.com/products/radioshack-npn-transistors-15-pack
The area Ben Heck used is fine if you just do ColecoVision cartridges but for that to work with Expansion Module one, you need to connect the non-ground line to the end of capacitor labelled C88 that is closest to the RF modulator.
Great video! We’re going to make another video soon building all the extras I could find for colecovision. I would love to add in your av mod as well. Colecovision rocks
Hi Paul! I found that transistor in an arduino kit. I got the info from google “ben heck colecovision” a (1) 1k variable potentiometer (Radio Shack # 271-280) (1) NPN transistor. Usually called a 2N4401-ND.
@@ChadDoebelin that's the only 1 I found also. He used a pot to adjust it. Wasn't sure if I needed it tho. I have like 5 to do and doesn't want to pay $25 each one. This is alot cheaper. But all the ones with boards have more than 3 or 4 pieces. There s a couple caps and other stuff. What kind of tv have you used it on. Have you tried yours on a larger flat screen. Wondering if it will work on a larger higher quality tv's
@@Mynameis7nad These are extremely common transistors. I just did this mod (I didn't use a potentiometer, just a 1K resistor) and it works a treat with a 2N2222, 2N3904, or 2N4401 which can be found at Radio Shack online: www.radioshack.com/products/radioshack-npn-transistors-15-pack
