I think what Ill do is buy a tester that can check the value of the caps as well as check the ESR and see what pops out at me. Totally agree, and this link is worth a read:http://www.diyaudio.com/forums/multi-way/282847-original-electrolytic-ca...

The caps I replaced were: the electrolytic, (2- 6.8uF , 2- 8uF, a 47uf and a 10uF) Also film caps, 3- 3.3uF, 2 -10uF and a 4.7uF.Two polarized electrolytic 2200uF, but these I replaced with electrolytics. C8=4X3.3uF=13.2uF and you replaced it wi...

If caps are parallel, measure it in circuit.

Just read the caps itself, you can compare the new caps with the existing caps which you took out from the crossover board.

How can I tell what the resistance should be, that device that Tim posted , will that tell me the correct resistance? If I measure the other crossover that I haven't changed any electrolytic caps out of yet. If I find out the correct resistanc...

With using just plain old zip cord I get better highs than the temporal continuums. Anyone have any idea why? What setting on the dials? on the highest?

I did replace two of three of the mid-range caps, as well as three of the five tweeter caps. Can you let us know which caps you replaced? the value of the caps ( ie: 2.2uF 100V)?

Converting Solid State to Tube Rectification on a Preamp
if i decided to do just a half wave rectifier using a single tube 6x5, is that possible?   Also, with the secondary measure at 350v, that is more than enough for a single 6x5 plate voltage? Sorry I don't have an answer for your question, but ... 
Converting Solid State to Tube Rectification on a Preamp
Oops!one more thing, as mentioned by salectric: the resulting B+ voltage will be lower than with a solid state rectifier, that may or may not be a problem.  
Converting Solid State to Tube Rectification on a Preamp
why would i change a solid state rect. to tube??? I am curious to see if a tube rect will outperform a solid states in my preamp. Using four rectifier tubes like 6AX4 to create a full-wave bridge and a 6V 5A power supply for heaters shoul...
