| Improve RFI @mahler123 said: I placed the transmitter -relay device on the floor next to the rack. Previously it had been on the top half of the rack, and then placed on top of a surround that is wall mounted at near the same height. The RFI light is off... | |
| Improve RFI @mahler123 , Not sure if this is any help. From the owner manual: Page 4 5. Observe the Status LED of the MRF-260. If it is glowing or flickering you must relocate the MRF-260 to a location where the LED doesn’t flicker. If your installation... | |
| Improve RFI @mahler123, Are you sure it is RFI and not EMI interference? You will measure a lot of EMI in front of the breakers in the electrical panel. (metal panel door open). Especially large running loads like the outdoors central air conditioner unit, a... | |
| Improve RFI @mahler123 said; I also have a surround sound system on the main floor; same AVR, same universal remote, and no RFI. Did you try using the main floor level remote in place of the one in the basement? What is the "firebox" in the basement? . | |
| Ethernet Wiring @mswale Said: It is perfectly safe to run cat6 inside ducting. In your opinion... It’s not NEC code compliant in HVAC supply air ducts. 06-11-2025 at 07:11am . | |
| Ethernet Wiring FWIW: NEC (National Electrical Code) 300.22(B) does not allow an Ethernet cable to be installed in HVAC supply air fabricated duct work for the use as a raceway. Even the exception doesn’t allow its’ use as a raceway. 300.22(B) Ducts Specifi... | |
| Can 6AJ8's be safely substituted for 6KA8's? NO. Not the same tube. Pinouts are not the same. 6AJ8 TRIODE - HEPTODE 6KA8 HIGH - MU TRIODE - SHARP CUTOFF PENTODE | |
| 15 amp vs 20 amp @bugredmachine Certainly understand that 15 amps will never be reached even with transients. As for transients. (Not to be confused with short duration of current draw pulses in a power amplifier’s power supply) You can’t measure transient ... | |
| 15 amp vs 20 amp FYI: Kil-a-watt will capture peaks. Didn’t use a handheld meter. Certainly understand that 15 amps will never be reached even with transients. My understanding only a scope will display very quick millisecond pulses, draws of current. https://... | |
| 15 amp vs 20 amp @bugredmachine Thanks for the kind words. . @bugredmachine said: On a side note, you would be quite surprised how few amps you really draw if you were to measure your wall outlet to the system running at a high level. In the past, a similar ... | |
| ??? Why Non Current Limiting Surge Protection ??? @freediver I agree with your ohms law analogy but it’s the high overvoltage event that causes the damage to the electronic components in the equipment. Example, if you fed a 120V power amp with 240V the higher voltage is what would fry the amp.... | |
| ??? Why Non Current Limiting Surge Protection ??? I’m confused about this..If current limiting is only applied during a power surge,why are they frowned upon for audio gear? During a power surge current is not the issue. Voltage is the problem. A high voltage power surge can/will cause damage ... | |
| Need a solid surge protector that’s non-current limiting. What is the difference between a thermal/magnetic and a mag only breaker? What is the different between a thermal/mag breaker and a mag only motor circuit protector? Product Line: Molded Case Circuit Breakers Resolution: The thermal/mag has bo... | |
| Ethernet Wiring @lovehifi22 , Project status? The cable would be inserted into the duct about 15’ away from the furnace plenum. I assume a straight shot through a 6" dia round supply duct to a ceiling mounted outlet vent register? (Naturally the ceiling r... | |
| Need a solid surge protector that’s non-current limiting. I installed a whole house surge protection and it was worth every penny. It is not nearly as expensive as people think and we installed the Siemens system. A Type 2 SPD is the first line of defense against transient surges. Be it a near by lig... |
