Class A.  Look at the size of those caps.  It's a very nice amp, but those caps aren't all that large. Physically, maybe, but 33KuF @ 35V? That's actually fairly typical. |

I think this thread needs to be revived. I love all of the old classic gear from my formative years in audio. I have a 29 year old Threshold S500 series 1, that I bought in 1986. I had it factory upgraded in 1993 to series 2, optical bias, E series in 1993. I still enjoy it's sound today hooked to a pair of Magnepan 1.7's in my living room.
I had occasion to pull it out of the shelf where it's kept and open it up the other day. For some reason, it blew a fuse...that's never happened before. I'm still not sure why it blew, but it was a AGC 12 amp 32 Volt one. I couldn't find one of those at Radio Shack or any of a multitude of auto supply stores around my house, they all had a 10 and 15 but no 12amp ones. I put a 10 amp one in temporarily while I wait for a 12 amp one that I ordered from amazon to arrive, and that has worked just fine. No more fuse issues.
I'm wondering if a two and a half hour power outage I experienced earlier in the day when it blew had anything to do with it. The power outage was due to an equipment failure with my electric utility company. I actually heard a pop or bang in the distance a few seconds before my lights went out. My equipment is pretty well protected from power issues. I have a whole house surge protector installed at my meter outside, as well as APC H15 power conditioners running all of my audio systems. It was turned off when the power went out so no current should have been going to the Threshold at that time.
Anyway, I took the top off the Threshold and looked at the innards, and after 29 years, the whole thing still looks like new inside. No corrosion anywhere, the 4 beer can size Mallory, made in USA 29,000 MFD 80Vdc, pos +85 degree C Caps still look perfect. No bulging or leaking at all. They made things to last.

Let's see here..I'm doing this from memory but the turntable itself was $1100.00, and the tonearm was $300.00. That was about 1980 or so. I went through a number cartridges on there...let's see..at first I was using a Great American Sound Sleeping Beauty, and then a Denon 103D moving coil. The current Shure V15 Vmr was added after CD's came in ...I know it was a 25th anniversary V15..special edition thing that came in a fancy walnut box. Since the original V15 was introduced in 1964...this 25th anniversary one must have been from 1989. I bet it doesn't have more than 10 or 12 hours of total use on it since then. I figured. That was a pretty penny back then. That's a great TT |

The original Oracle turntable..made in Quebec. With a Magnepan Unitrac I tonearm and Shure V15 type V mr cartridge. Not many people know that Magnepan actually did make a very impressive carbon fiber tonearm. It still works great and is hooked up in my main system. I seldom use it though.  That really is a beauty. I really like the Shure carts as well. They just have the tonal balance that I enjoy listening to. I have the Shure V15 IV on my TT. It blows away the new M97xe that I bought that now sits in my closet as a spare. I've always liked the sound that the Shure V15 series cartridges produced. That V15 type V MR has the little brush thing on hydrualic hinges that rides in the record groove ahead of the stylus. It brushes debris from the grooves, but more importantly, it keeps the tonearm under better control. I have one Telarc LP of the 1812 overture, with real cannon shots. You can see by looking at the surface of the LP where the cannon shots are. That sequence would send most tonearm/cartridge combos jumping out of the groove and skittering across the record. Not with the V15 V and it's hydraulic stabilizer brush. |

Look at the size of those caps.
