You can do it yourself but you need some equipment and probably isn't worth it. The cheapest option is the Radio Shack SPL meter. It is decently accurate(especially the new model) at low frequencies but isn't great above 6 KHz or so. The better option is to buy a measurement microphone...
Don't waste your money. There should be no reason that you can't place your TV far enough out of the way of the sub. It doesn't need to be a huge distance...just a few feet usually.
You will want to be careful about doing that. Your TV is a CRT and your sub will not be shielded. Placing it on top could lead to some stray magnetic fields interfering with the electron gun's accuracy(leading to color corruption)
Something seems wrong to me with what your doing or you have a short SOMEWHERE if you have gone through receivers that quickly. I own a 435 and have had no problems.
I always thought that the rf was just a passthrough on the VCR and that the only way to output the rf in was through the rf out...could be mistaken though. Aren't there cable boxes that output other than rf? You would have to ditch the cablecard though. Even if they only output...
Oh if you check out my posts at AVSforum, They have already done that, it shipped out today, all is wonderful :). Of course, I plan on keeping both! Two remotes = twice the fun ;)
I love my new receiver. It has every feature I wanted and did not disappoint. For me, because I lived with a entry level receiver for so long, its the little things that I am enjoying the most. No more guillitine clamps for speaker wire, individual crossovers for each speaker, hell my last...
Just took a look and its not running. I doubt it will in most cases. That is a REALLY big heatsink. Even though the receiver gets quite hot, the heatsink most likely can handle the heat dissappation on its own. I wouldn't worry
