I have built many Heathkits back in the day including the H8 computer. The Crack is my first project in a long time. Thanks to lurking in the forum I caught an error that would have been a pain to correct later and fixed it. Otherwise everything went smoothly. Resistance and voltage checks were right on. Fired it up and put on the HD600s and listened to "I Remember You" by Diane Schurr. It was awesome.
The only difficulty I had was due to my vision. I am 67 and my never great eyes are now definitely showing their age. I was having a lot of trouble with depth perception leading to putting a hot iron where I didn't want it. I bought an Amscope stereo microscope and used the 5 power lenses and it worked great. Required a little getting used to but made things much easier and was great for inspecting solder joints. I tried a headband magnifier which helped and would probably work for most people but I need slightly different strengths in each eye and I can do that with the scope. I will be building the Speedball in the future and I am sure it will help with that. And, after all the projects are complete, it will make a great gift for the grandson.
Just wanted to say thanks for a great amp. Got to get back to listening now!
