| 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 ... | |
| 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... | |
| 15 amp vs 20 amp Assume the 15 amp unit will have #14awg internal wiring. (wire rated for 15 amps) Assume the 20 amp unit will have #12awg minimum internal wiring. (wire rated for 20 amps, minimum) Assume all other components in the 20A unit is rated for 20 amps... | |
| Ethernet Wiring Interesting... CAT5, 4 pair UTP Ethernet cable was first introduced in 1995. . CAT3, 4 pair UTP Ethernet cable was first introduced in 1991. Good for voice, not so much for data though, as I recall. Installed miles of RG62/U coax cable in... | |
| Ethernet Wiring Technically, this would meet building code. 3M Fire Barrier 1.45 in. x 6 in. Moldable Putty Stix MP+ Flexible 76 | |
| Ethernet Wiring It can be installed in the air return ducting. You will need to use plenum fire rated jacketed cable though. Other options for running the cable? Is the floor in the room pad and carpeted? It is possible the cable could be installed around the ... | |
| Looking for Solid Core Speaker cables As my speakers have 99db or more efficiency I definitely dont need thick wires. I am thinking 2x18awg and 2x20awg at the max or even 4x20awg. I know not typical orthodoxy but Acoustic Revive and Morrow (and DNM) seem on similar path.. @total111... | |
| Looking for Solid Core Speaker cables . @total111 said: 05-30-2025 at 02:26pm Second, when I said "solid core" I had a very narrow definition in my mind. Max. 2 strands in a twisted pair (or star-quad) configuration or very similar minimalistic approaches. The mentioned Kimber ... | |
| Thoughts on Iconoclast interconnects? FYI, Iconoclast cables were designed by Galen Gareis when he worked at Belden Cable. Belden manufactures the Iconoclast cables and sells bulk cable to Blue Jeans Cable. Blue Jeans installs the interconnect connectors and speaker cable termination... | |
| Synergistic Grounding Block and Tweaking it. I arrived late to the conversation, I will receive the passive device in a few days, I wanted to know if anyone tested connecting it to the negative pole of the speaker cable, at the end (connection to the speaker), if so, did you like the result... |
