! The ToneGenerator Filter Capacitors
The wax-and-paper caps used in the filter networks on the ToneGenerator degrade like all the others. However, if you are considering replacing yours, __be advised__ that ''whether'' and ''how'' to [replace the ToneGenerator capacitors|ToneGeneratorCapacitorReplacement] is a ''hotly debated'' subject.

+Replacing aged capacitors in the vibrato delay line box is probably less controversial.

+StefanVorkoetter has written a nice [article|http://www.stefanv.com/electronics/hammond_vibrato_mod.html] on how to do this.
+(His site also suggests some improvements to the vibrato in the M-100 series spinet models.)

! Mounting Replacement Capacitors
Most often, many of the electrolytic capacitors needing replacement are of the multi-section can type. These caps usually plug into sockets, and protrude from the top of your (pre-)amp chassis --- each aluminum can actually contains several (two to four) separate capacitors. These capacitors are no longer manufactured (well, there are some manufactured in Mexico, but their quality is highly suspect), so generally one needs to replace them with individual capacitors.
(Another alternative is provided by ZackEngineering, who makes replacement multi-section capacitors from modern miniturized electrolytics.) (Yet another alternative is FrontierCapacitor, who, reportedly, will "rebuild" your multi-section can caps for you --- removing the old guts and replacing them with modern caps.)
+(And yet another place which seems to be custom-building multi-section caps: [askjanfirst.de|http://www.askjanfirst.de/eindex.htm].)
How then to mount the replacement capacitors? Here's what I do:
* Unsolder all the connections from the old can caps, but leave them in place. Otherwise you'll have holes in the chassis which you'll want to cover or plug.
