| Thorens 160MKII BC Grace 707 + F9???? If you look up the compliance data for the F9E vs the F9Ruby, I really do not think you would find much if any difference in compliance. Your finding that the Ruby was bright and hard in your system does not at all gibe with my experience in my sy... | |
| Thorens 160MKII BC Grace 707 + F9???? I dunno if the 707 is amazing, but I do know it will work fine with the Grace cartridge of the same era. Why not give the Thorens/Grace tonearm/Grace cartridge combo a listen for a few weeks. If you are dissatisfied at that point, you can then ma... | |
| Thorens 160MKII BC Grace 707 + F9???? The OP won't spend to repair the Luxman. Why would he spend several hundred more dollars to replace the perfectly good tonearm he received with his replacement turntable? And for the Grace F9, it is not at all clear that the Acos would be signific... | |
| Allnic OTL/OCL Phono vs Allnic DHT Was wondering how or even if the floating PS as used by Atmasphere in the circlotron could be implemented in a SE output. | |
| Thorens 160MKII BC Grace 707 + F9???? What would make you think that a Grace tonearm marketed contemporaneously with a Grace cartridge would not be a good match? | |
| Luxman PD121A - PD441 Did you or the previous owner ever connect it directly to 120V? The repair scenario suggested by Dover should not cost more than an hour of technician time. Surely that’s worth doing. I don’t know your location but Music Technology in Springfield... | |
| Luxman PD121A - PD441 Dover is essentially saying don't give up, and I agree with him. You have a very nice TT there. Funnily, if it is a 120V unit and you are using a 120V to 100V stepdown, that may negatively affect performance. Line frequency 50 vs 60Hz does not ma... | |
| Allnic OTL/OCL Phono vs Allnic DHT “Some circuit experts might be concerned about DC potential in the music signal in an OTL/OCL design. However, the chance of this problem occurring can be essentially and reliably 100% mitigated. To do this, Allnic uses a “floating power supply c... | |
| Luxman PD121A - PD441 “50/60” is a reference to AC frequency not voltage. Somewhere on the chassis near the AC outlet or the fixed AC cord outlet there will be a recommended voltage noted. Probably that’s not your problem but worth checking. | |
| ADC moving-iron cartridge has "low" output I would not say “fake” but once or twice they’ve sold styli they described as “original” which implied OEM, when in fact what they were selling was a reproduction of OEM. No problem with functionality however. | |
| ADC moving-iron cartridge has "low" output Elliot, you have a point. I chose to use 3.54 cm/sec as a standard because 30 or more years ago, that was the standard stylus velocity for calculating output. But you’re correct that in the last few decades, 5cm/sec has become standard. I chose th... | |
| VPI TNT 3 I remember noticing you originally were using a Sumiko BPS. That’s one of the HOMC cartridges that convinced me I don’t like HOMC cartridges. Good move to the Koetsu. | |
| Luxman PD121A - PD441 First, determine whether your new TT was built for 100V (Western Japan) or for the US (120V). If it was built for 100V, you meed a 120V to 100V stepdown transformer. A stepdown with 50W capacity is fine, and they are cheap on eBay. If it is a 10... | |
| ADC moving-iron cartridge has "low" output It’s not “different”, it’s just another way of stating output, in this case with respect to stylus velocity. In those days the standard stylus velocity was 3.54 cm/sec. If you multiply that velocity by 0.9, you get around 3.2 mV, which is a bit le... | |
| ADC moving-iron cartridge has "low" output What yogi said rings a bell. When OP said the XLM has output 5.5 mV, that sounded incorrect based only on my fading memory. So I looked it up and also found 5.5mV at the LP Gear website. Memory says its output is less than that of a typical MM. An... |
