Thanks very much for explaining the resistors and heat vent.
BTW, I saw some pictures of your crack with speedball...very neat and nice. Wondering how the holes were cut on the carbon fiber around the vent?
I am also quite curious to know how the huge capacitors and the resistor cylinder that you added can improve the Crack with speedball? What do they do?
I used a dremel with different attachments to cut out the slots and holes in the carbon using the holes in the alloy top plate which is stuck to it as a guide.
The capacitors can have quiet a effect on the sound, generally speaking for this application the higher the quality of capacitor the easier it is for the audio frequencies to pass through with the least amount of degradation to them, hopefully resulting in a truer more detailed sound. The difference is kind off like looking through a clean window compared to a dirty one. You get a clearer sonic picture.
The two small capacitors are Valab polypropylene in oil film capacitors 47uf each and the larger one on top is a high quality 10uf RTI Teflon capacitor which is used as a bypass for the two 47uf film ones. These replace the stock electrolytic coupling capacitors.
The resistor cylinder is a 23 stepped attenuator (volume control) simply it again provides a shorter less resistive path for the signal to travel, less resistance means more details get through.
There are more details on the mods in the link
