Yes, the two problems were that the rest of the albums were really expensive, and the choice wasn't that great. If I remember, you had to choose the full priced monthly albums from a small list. Between Columbia House and BMG, I probably signed up 3-4 times over the years. Several times I just ignored the followup letters. I'm pretty sure CH dinged my credit back in the 80's.

My dad and I signed up quite a few times. It was fine as long as you purchased the expensive album and then canceled. It was still worth it.

Gotcha. Possibly, some people on the forum may still have their old broken motors if they replaced with a different fan. I'd suggest doing a search for fan replacement threads and then contact those people.

It appears there are no plenty of them available. These seem to be newly manufactured by the same company that made them 40 yrs ago. https://www.ebay.com/itm/124496927399?fbclid=IwAR3KrOFEH9iICLmAP_FW4c-Xj9p57_oujCkrw1SIGwEI0_xzNOvj6ElR-kQ

This may be stating the obvious, but you do know that there are a host of operating and service manuals on this site? Here is the schematic for the M500t: https://thecarversite.com/manuals/mandir/Carver M-500t service manual.pdf

The $35 shipping is interesting.. you can send it by Media Mail for about $3 bucks. Don't know what insurance would cost though

Damn, I knew I should have bought some of those discs way back when! I have several sealed copies of dark side of the Moon, one of steely Dan Asia and a couple of others that I don't really remember that are in my garage, but they're all the original omr recordings, not the uhqr ones.

Sorry, I wasn't real clear in my questions/comment.. Mobile Fidelity Sound Labs first produced their audiophile Original Master Recordings, OMR, in the 70s. Then in the early 80s they came out with their UHQR, Ultra High Quality Recordings, which were on heavier vinyl, and used JVCs proprietary Supervinyl. I was wondering if that super vinyl is the same as today's super vinyl. They also changed some of the mastering and pressing techniques to make the discs better as well. They were about double the cost of their regular O My R discs. So I didn't know if they were really worth the price back then. I quickly tried to look up exactly what was different in the uhqr disks, but wasn't able to find anything specific. There is a little bit of info on the new Mofi website, and Wikipedia In 1977 Mobile Fidelity began to produce a line of records known as "Original Master Recording" vinyl LPs. These albums were previously released by other companies, licensed by Mobile Fidelity, and remastered by a process called half-speed mastering. During mastering, sound was transferred from magnetic tape to disc while the cutting lathe moved at half speed. The albums were remastered from the original analog master tapes, without compression, and with minimal equalization. The recordings were pressed in Japan on "Supervinyl", a plastic compound invented by JVC to compensate for the demands of quadraphonic Compatible Discrete 4 records, which had been introduced in 1972. JVC Supervinyl was more durable than regular vinyl, with lower surface noise and fewer pops and clicks. Mobile Fidelity packaged their albums in heavy cardboard sleeves, inner cardboard stiffeners, and plastic liners

Interesting. Is this the same way they did it 30-40 yrs ago when they first introduced it?

Wow! I've got quite a MFSL vinyl discs, but none of the ultra discs, because I just didn't see why they would be any better simply because they're 120 g heavier. Lol Also have a bunch of Sheffield Lab discs, and Nautilus Superdiscs. Telarc made some great classical recordings as audiophile discs as well. Including one of the most famous records ever... Tchaikovsky's 1812 Overture. You can actually visibly see the 6Hz cannon shot grooves with your naked eye. Only one cartridge that I know of was ever able to track that groove, and that was the Shure V15 type V. Now, if I could only find an exact replacement for that cartridge... Sigh

I'd probably repost in: https://thecarversite.com/forum/25-carver-pro-amps/ Also, your service and instruction manuals can be found here: https://thecarversite.com/carvermanuals/

True...I guess I meant to "repost" it .

You might want to move your post to another one of the more applicable sections of the forum.

Actually, for a good audio cable it's actually pretty negligible. For a 3-ft long cable, of good quality, you would expect less than 50 pF. However, I don't really know what the recommended loading is for today's phono cartridges, especially moving coil. Back in the day, people rarely used moving coils simply because of their extremely high cost, very delicate nature and the fact that we had plenty of moving magnet cartridges that were outstanding. The selection of cartridges today is dramatically smaller. RIP Shure V15 Type V MR I have two of the above with the stylus in excellent condition, but my guess is the rubber compliance parts after 30-40 years are probably not in good condition.

From Denon's User guide: Load Impedance 100 ohms min. (40 ohms when using a transformer) On my 1980 Pioneer SA-9800 integrated amp, there are also settings for capacitance. Do you have to worry about that? The settings available for moving magnets are: 100, 200, 300, 400, 500 pF 100, 10k, 25k, 50k, 100k Ohms
