Building Up a Stock Supply Question

My question revolves around wanting to build up a stock supply of capacitors, resistors, etc to have on hand as I begin to repair/recap vintage Kenwood stereo equipment. Currently I have the following units:
Kenwood KA-3500
Kenwod KA-6000
Kenwood KT-7000
Kenwood KC-6060

For the KA-3500 I purchased a "recap kit" but it occurs to me it's cheaper to just get individual components myself. Having said this I am assuming there must be some typical or standard size capacitors, resistors, etc commonly used and if that is true I would like to work on having a stock supply so I don't have to place orders every time an issue arises. It also seems to make sense to me that if I am going to orderna few items for a recapping/repair job that it would be smart to get multiple units and save on shipping.

Does anyone know if there are some common size components and if so what they might be? How have others build up a stock supply when first starting out?

thank you

There are no "typical" sized parts that covers everything.

Order parts as you go, get extras, and familiarize yourself with which type part is used in which circuits/configurations.

Look through the forums to see what people have asked about and what responses were given in regards to the unit you're interested in.
 
Look through your gear that want to restore. There will be many small orange caps, these are low leakage type electrolytic capacitors. For these types you want to use Nichicon UKL. Then look at the values for the power supplies. For the power supply stock up on Nichicon UPW.
 
Ok I am about to figure an order from either Digitkey and/or Mouser but have question. I had ordered a recap kit when I started out for a Kewood KT-7000. The kit came with for instance 3.3 μf/100v. Currently in place there are 3.3μf/16v. In looking at Mouser I see 3.3μf/25v, 35v even 50v. Is jumping from 16 to 100 volts of any concern? I've read its ok to go up but wonder if that is a limit where one would say "Nope" 2.

Some will probably disagree, but I don't think it will be an issue in terms of performance. The only problem that might crop up is physical size and lead spacing, but new parts are usually so much smaller than the old ones it's rarely a problem.

When I'm recapping stuff I look at the actual circuit voltages compared to the cap voltage ratings that are installed. Some gear, like Soundcraftsmen, used caps rated just a couple volts over the circuit voltage which is not good for reliability or longevity. Using higher voltage rated parts should get longer life from the parts, so if a device I'm recapping uses 10 uF caps rated for 16, 25, 35V, I will buy and install a bunch of 10 uF 50V parts. That helps keep cost down and reliability up.
