If my car was overheating because of excessive load I would probably swap in a larger radiator. The amp will never die, it can be rebuilt, heck last summer I replaced everything except a handful of parts (WOPL build). I love my Ohm speakers, Love my WOPL 700B, gonna pound the amp and the...

I need to add some fans to me PL 700B, they drive a pair of 4 ohm speakers (Ohm Is), and the amp does get hot, and will shutdown if I run it too long at a high volumes. The pros had trouble cooling these amps when they were used for sound reinforcement, I doubt a couple of muffin fans will be...

Sad, just saw Peter Wolf in concert Saturday night, guy still has it, moves like a teenager, and his voice is as good as it ever was.

Thanks Ed, that's so cool to see a picture of the person that built the amp. Although after a full WOPL treatment including a new chassis, there is not much left that Ruth would have done. But great to see the history of the amp.

My 700b was a "Ruth", unknown SN, tag unreadable, but seems like an early one (non cam off switch, metal knobs).

That does not sound like clipping. When you have clipping the amplifier is distorting on the peaks, sounds bad, and is worse for your speakers especially the delicate tweeters. What you have sounds like your equipment is going into protection.Most likely because of overheating. What is the...

30 Hz is pretty good, just be careful and do not send sine-wave at high/full volume, this is very stressful for amps, and I imagine speakers. Good for testing at lower volumes and with a scope for diagnostics.

Transmitters are pretty boring these days, I worked in a radio room where an old UHF TV transmitter was serviced by walk-in. Another story: when we were digging a trench to feed power to a hut at the base of an AM station we hit and severed their transmission line, It was spliced back together...

Too bad it's not a 50,000 watt clear channel station, then you could hear the music in your dental fillings.

I have heard good things in regard to the airport express, that was going to be my second choice, but I already owned the Chromecast Audio device, so that is where I started. Don't think I could hear anything audio wise over 256kb sampling, I will have to experiment with a high quality CD and...

How do you play the MP3s?

For about a year I have been listening to digital music from my iPad to my Pioneer SX-950 using a headphone to RCA cable. Sound was OK, some albums sounded better than others. Most of the music was ripped from CDs at 256bit rate. In another thread I noted that I picked up a reel to reel, the...

tiddler= A young or unusually small person or thing. example ‘she was only a little tiddler, ten years old’ Hey, I must not be the only one that needed to look that up.

you said butt, Ha!

Welcom , lots of good stuff here, hour and hours of reading in the history thread, master techs that are amazing at remote diagnostics and help with repairs.

Thanks Nando, yes I am using the SX-950 as a pre-amp, and using it to drive the WOPL. The SX-950 stays nice and cool that way, no problem stacking the reel to reel on top of it. I will be looking for a better way to set up the equipment, but for now that table works fine. I did get a manual...

I would be happy to send you the contact info of the gentleman that sold me my deck. He seems to know his stuff, but shipping on the 909 would cost a few $$.

I have wanted a reel to reel deck for a long time, although for the life of me the only reason I can think of is because they are cool. I can do everything a reel to reel does from my iPad, but the ipad is not cool. I grabbed a Pioneer RT-909 off of the list, had to drive 200 miles, but it was...

I use one of these for my 700B, yes the 700B has a built in power switch, but it is old and fragile. I do get a small pop on the speakers when I turn the receiver/amp off, nothing huge that I can't live with...
