Whole house surge protection
Jea, IME MOV have given me problems. I've had a strip that used MOVs and it kept tripping my circuit breaker. When I disconnected it, issue solved, but I had no way of knowing if the MOV inside the strip was damaged or still working. Read below.ht... 
Does the volume control effect sound quality?
Atmashere, you raise an important point. I was thinking of replacing the stepped resistor attenuator (Goldpoint, 100kOhm) with an inductive volume control in my amp that uses a 12AX7 followed by 12AT7. The stepped attneuator sounds great. I want t...

Schipo, my ac plugs are made of 99% copper and shows signs of wear, and the flimsy AC outlets are becoming loose because the plugs fit very tightly.

Thanks Photon. Appreciate the response.

Gbart, do those technologies limit current to the extent you'd notice dynamic compression?

"But of course the only sure way of providing complete protection from lightning strikes is to unplug your gear during bad storms." That's what I've been doing after each listening session, and it's a PITA and wears out the AC outlet and plugs.I'v... 
O.C.D. Speaker placement
IME, the sweet spot does change depending on where you place your speaker in the room among other variables. I've spend two years treating my dedicated audio room with acoustic diffusors and absorbers, changing the speaker and listening positions,... 
O.C.D. Speaker placement
Depends on the speaker. Some are more forgiving of speaker placement than others. You can follow the manufacturers recommendation as an initial guide line, but the final placement is very dependent on the room (size, shape, acoustic treatment, you... 
Bob Carver LLC Black Beauty Review
Oh yea, I've been meaning to replace the input resistor as well. As far as resistors go, this resistor probably has the most influence in the sound. It needs to be 3.3 kOhm, 0.5 watt resistor with 300 V rating. May be a Shinkoh metal film, nude Z-... 
Bob Carver 180 Mono-blocks perform superbly
Bob Carver tube amp owners should unite and ask for stepped volume control and better output coupling caps as upgrade options. They're easy upgrades that significantly improves the sound. 
Bob Carver LLC Black Beauty Review
Kenster, I'm not a blood sucker (DraculA)...I think you have me confused with my ex. If you open up the one mono block chassis, you should see two 0.22 uF caps, one for each bank of push pull output tubes. Those are the coupling caps you need to r... 
Bob Carver LLC Black Beauty Review
Dragon, personally I think the sweet spot is with the Cherry 180, if you don't need the extra power. I'v heard both amps, but not in direct comparison. I was told the Black Beauty might be a little more sweet sounding, but that may be due to the K... 
Does the volume control effect sound quality?
YES! Most amp manufacturers will put in the cheapest volume pot in their amps. You'll notice the biggest improvement by swithching to a stepped resistor or transformer/autoformer volume control. LDRs will also give you a big benefit, but I don't k... 
What is the best loudspeaker for a small room?
If you gots the money, why not the new Raidho D1 with the diamond midrange/woofer driver and ribbon teeter? You definately have the appropriate electronics to drive them. They're small and will fill your room with wall of focused sound. I've liste... 
Bob Carver 180 Mono-blocks perform superbly
Ah yes, I remember this story of Bob and Stu Hegeman. The best designers of the glory tube years would never consider designing a SET amp, including Bob. It was PP class AB amps all the way, and to my ears they are more neutral than any SET amp I'...
