I generally like to see more actual work being done. Maybe a tripod or even a stack of books for the camera? But I do understand that "lecture" style videos can have some educational value. My attention span is just too short to take it all in without seeing some of the operation in progress.
Check out some of my other videos. I do soldering and detailed work on them. For example, my video on repairing the reverb on a Deluxe reverb. Some have complained that my videos were to long, so not showing all the work speeds things up. Also, my intent on this video was not to teach soldering, cleaning, and parts replacement techniques. Finally, I sometimes use a camera person or tripod, sometimes I don't.
Lets talk about two brands- Sprague and Illinois in a filter capacitor application. Sprague Atom capacitors are popular for several reasons. They are a nostalgic brand with a lot of brand recognition since they were installed in lots of vintage amps, they are really nice looking and at a high price point that many confuse with quality. I'm not saying they aren't good or maybe even the best quality, but there are other brands of capacitors that are also of good quality. I have most often used Spragues in vintage amps because there is a perception of quality that goes along with them. But if cost is a consideration, then I think a less expensive brand is OK. Compare prices- Sprague Atom 80 Mfd @ 450v is $ 13.25 whereas the Illinois brand of the same values are $5.80. Both Sprague Atom and Illinois Cap, Inc aluminum electrolytic capacitors are rated at 85 degrees C. and have the same stated tolerances. As far as reliability, I haven't seen a significant number of failures of either brand except for ones that are really old and start to leak and then fail. The more important thing that can be done to ensure long term reliability is to use higher rated voltage caps. For example, if the max voltage in a circuit is 350 volts dc, then a 350 volt rated cap will not last nearly as long as one rated at 400 or 450volts. Some equipment manufacturers may cut that safety factor too close, shortening the life of the component. So, it might not be the fault of the capacitor that fails but rather the designer/manufacturer.
one of the best amps ever! thanks.
I've done this job a thousand times resistors and caps 3 x 20uf-500v 2 x 100uf-300v 5 x 25uf-25v
Great job !.
Great video. Where are you located and how much did this work cost the customer?
Send me an email at jamelectronics@bellsouth.net and we can discuss

I have always heard that the Illinois brand are the worst ones you could get. Fender puts them in their amps and have a lot go bad.

Illinois caps are like the worst ones made these days. F&T would be better.
