| Krell 350 MCX Coupling Cap Jumpers This is the first time I heard of restrictions using a SS amp with a tube preamp, is this specific to Krell? Designer's decision! He didn't want the leaky coupling caps in a tube preamp (some vintage/boutique PIO caps tend to leak) damaging dow... | |
| Krell 350 MCX Coupling Cap Jumpers The red circles are the two coupling film capacitors, next to them are the jumpers (green circles). Removing the black plastic jumpers will activate the coupling caps. | |
| Looking for a phonostage similar to stock one in RA180 I tried a few from $1000 to $5000 and could not get that sound. If you have no noise issues with other phono stages, your RA180 may need service/repair. | |
| Preamp 47K load. Cartridge needs 330 ohm Where is the OP going to find a SUT with a 1:12 step up ratio? | |
| Looking for a phonostage similar to stock one in RA180 I never heard a better phonostage in my system. The only drawback is - it is extremely noisy. According to Stereophile review JA's measurement: I examined the phono input's adjustable equalization set to "RIAA" and the output measured at the... | |
| Handling Heavy Amps If I buy from my dealer he’ll load it in my SUV. However when I get home it will be difficult to get it out and onto the garage floor where I can place it on my handcart. Then when I get it next to my rack I need to maneuver it out of the box and... | |
| how to test tubes with your multimeter(filament continuity) I get the idea that that a tube with continuity may still be bad but will not cause catastrophic damage to the amp that it is inserted in. Not really, a shorted tube can cause damage to the amp. Simple tests for Tubes with a Multi Meter | |
| Accuphase E-280 Voltage Conversion (100V to 120V) I suppose the last picture above is the post-modification (working at 120v) ? @jcgoobee Yes, if your E-280 has the same connections and color coded wires. 120V connection: 100V connection: | |

| Luxman 505uxii Class A/B operation According to my observation, class A power of an class AB amplifier is approximately 10% of its idle power consumption. The 505uXII idle power consumption (no signal) is 85 watts. I estimate its Class A power to be about 4 to 5 watts per channel. ... | |
| XLR to RCA conversion I am wondering if the PC-2XR will work. I think it should work and if you order from PE it comes with a 60 day no hassle return policy. | |

| Harman kardon a300 rebuild Well, everyone starts as a beginner. 😊 According to the schematic I would use 100μF for C23 and C24A, higher voltage rating wouldn’t hurt either. I don’t know why 650Ω and not 470Ω, you can try both for best performance. BTW, since you are rebui... | |
| Harman kardon a300 rebuild Please refer to the schematic, There are total of three filter capacitors in its power supply: one 100µF 200V can, one 50µF 400V + 100µF 200V can and one 3X 40µF can. Are you talking about the 50µF 400V + 100µF 200V can? It is two capacitors ins... |
