I think Glen posted fairly recently about having one of those.

Sweet.

The volume pots on my 700B were deactivated for simplicity’s sake. The pots are still there for something to keep the (unused) knobs in place. But….when preamps have stepped volume controls, being able to attenuate the power amp would be useful. Circumstances dictate that my listening...

Count me in for best birthday wishes too.

I’m fairly optimistic about one or both of the 2SA798 being the noise source. From what I’ve read, they have somewhat of a reputation for degrading and possibly becoming noise producers. I am compelled to think that their black legs are a strong indicator. Glen was kind enough to provide a...

I can't totally rule out anything but the noise was not described as cracking. It was said to be a "pop" which I was told happened intermittently during the day without laying a finger on the amp. The shop owner explained it was her concern about speaker damage that prompted swapping the...

The compressor is acoustically isolated in its own chamber or room.

It's an integrated amp and yes, it does work. When I got it home, I checked for DC before connecting speakers. That was when I noticed the indicator lamp was not lighting up. There was some offset, less than 50mv per channel, so I hooked up speakers and an AUX source. It played for an hour...

The only thing I know for sure is that the lamp bulb inside the amp is dead. If characteristics of the 12 volt and 8 volt bulbs I experimented with, prevented them from illuminating when power is switched on, could be then that the only solution is a new bulb with exactly the same specs as the...

What are the chances of that 2W 680 ohm resistor exhibiting a high resistance only when under load? I removed it from the circuit board and saw the number of the beast - it measured 666 ohms.

Thank you Lee, thank you Mark. A few years ago I replaced twin transistors in a small Sansui amplifier but can't remember if they were also 2SA798. Since I've run into them again, I'm prone to think they were. I successfully replaced them with back to back TO92's that were likely KSA992 as I...

I am hoping someone can provide insight into this. I have replaced lamp bulbs before and it was a fairly cut and dried process. Yesterday I visited someone who recently purchased a record store. Because I got some of her 2nd hand vintage turntables to work, she handed me a Pioneer SA700 II...

Agreed. The only Fleetwood Mac album I had for decades was Kiln House (1970) and the cover was her artwork.

So, buy first and ask questions later?

There is a big park a few blocks from me where my dog Milo and I spend a lot of time. There are lots of sculptures scattered around this town and one in the park is particularly odd. Someone told me it's called "The Troll". Milo growled and barked the first few times he saw it. Too bad...

Anyone watch the R&R Hall of Fame induction on Saturday? I missed the first half but enjoyed Judas Priest performing. A more portly Rob Halford with a white beard and the band can still do a job. For some reason, Dolly Parton got inducted. I had a laugh at the end. Participants all on...

I have a lower model Extech DMM and from the get go, it's slow, auto ranging is unreliable and after two years, the function switch must be fiddled with sometimes to activate the meter. If/when I purchase another meter, it will not be an Extech. For the time being though, it will have to do...

And I bet you can't use a Discwasher.

There was someone, Willie Joe, that made and played a seven foot long "Unitar". I have a 78RPM copy of "Unitar Rock" from 1956 and it does sound odd.

I've got a basic Sencore (Mighty Mite I think) and it makes me chuckle that it incorporates a tube so that it can test tubes.
