I numbered my questions 1-4
I'm looking to purchase parts for my tr 808 but I'm some what confused. I want to start by recapping, replacing diodes, replace switches for the 16 steps, and then re-calibrate it.
The problem is that I'm not 100% sure what kind of diodes to purchase. I have the service manual printed out (linked below)
**broken link removed**
in the parts list they have
Diodes
15019120 IS2473 Si Diode
15019122 IS188FM Ge Diode
15019236 W-02 Rectifier stack
15019209 10E-2
However my friend told me to use 1N4148 High Speed Switching Diode and to "replace all" (
1N4148 High speed Switching Diode by Philips Semiconductor )
1. Should I replace all diodes with these 1N4148? or just the Silicon ones?
2. Is the 1N4148 a Silicon or Germanium Diode?
I plan on buying Panasonic FM and FC from digikey
I heard you can put slightly higher farad value caps in for the PSU
3. What is the highest/best value I can put in for the PSU caps?
I've done some searching on threads

I'd like to do the Kenton Midi Mod, is there anything from this mans superb work you would recommend that I do to my tr808?
4. Do you guys think the re-soldering all pads i.e heating up solder points to let them reflow is really necessary?
