| Tube Question is 5687 tube same as 5687WA?? I don't know what WA actually stands for but it indicates a ruggedized tube designed for industrial and military applications. It can be substitued for a 5687, and a 5687 can be substituted for a 5687WA in most audio applications since it will not... | |
| Vinyl manufacturers don't stand behind product? A shop near me told me the same thing, the distributors won't take it back. I guess it is up to the retailer whether they want to eat the return. I checked Music Direct's web site and they exchange defective LPs. Probably a bigger operation than y... | |
| Power supply variations- I forgot to mention that some warts are AC and some are DC, that also must match the original. | |
| Power supply variations- Are you sure it is millivolts and not milliamps? 800 millivolts is too low to operate most stuff.Wall warts are rated for:The amount of voltage they develop; this MUST be the same as the one that is replaced. The maximum amount of current they can... | |

| How can I safely remove Optrix from my CDs? Hi precbsed, did the manufacturer have any explanation for this cloudiness? Did they produce a bad batch of this stuff or is just not a good product? It must be undesireable to have it cloud up or they would not have advised how to remove it. | |
| How to bias... Easiest to use is an auto-ranging digital meter, less than $50. You want to use the DC voltage setting. The manual should tell you how to do this. Maybe the guy at RS will know but I doubt it. Be careful. If you ask he will try to sell you a cell ... | |
| Best SET Compatible Speakers, $4k-6k used Yes, I forgot about the Brentworth. I have heard them and they are very good. I assume they are still in business as their website is still active. Worth checking out. | |
| Help, I'm going crazy with vinyl noise In case anyone is interested, I found the problem. The sound had gotten much worse so I took off the cartridge to inspect it. My eyes aren't that good and I can't see the stylus very well when it is mounted. I gently pulled on the cantilever and i... | |
| DYI diffuser kits/plans I have also searched for info on this but this is the best I have found. There is enough here to build some but it doesn't give details on how to calculate the upper and lower cutoff frequencies, just some examples. | |
| Best SET Compatible Speakers, $4k-6k used Twl is correct, the Lamhorns would be an excellent choice and can be had new for less than $6K with a choice of drivers. I have DX3 in mine. I would have gone with AER but they are 16 ohm only and my amp is 8. I think they come in 8 ohm now but I'... | |
| SACD - what gives? The answer to your question is very simple. For the most part, they don't exist. To have them means that the recording studios have to convert to machines capable of making these recordings. If you ask the same question about DVD-A recordings you ... | |
| I recently emailed John Atkinson of Stereophile I've gotten stuck with "The Audiophile Voice" several times. Recently when "Listener" folded, when the "Tracking Angle" folded and it seems like when FI went under.The only redeeming quality is that it takes so little time to go through it that yo... | |
| Any electronics wizards? Tube problem with RM-9 There is a negative DC bias voltage applied to the grids of the tubes. If you lose this voltage the tubes will run wide open and blow the fuses. That is a likely explanation. A cold solder joint in the bias circuits could be the culprit or some pa... | |
| Wash, Cut, Polish & Demagnetize I found this site about how compact discs work that may shed a little light on the topic. |
