    APM-200 VU Meters, open?

    Be careful when those needles are exposed and unprotected. I had an old VTVM that I had the needles exposed and found out the hard way just how fragile they can be.

    Is this a fair deal for Phase Linear amps?

    I think $250 for a PL400 is a good deal. You'll want to at minimum install a Watts Abundant speaker protection relay. After that possibly do a White Oak Audio modification consisting of just the control board or full conversion to full complimentary upgrade from the stock quasi-complimentary...

    Can i connect g7500 sansuai to altec lansing 508 4ohm speakers?

    Per this review Altec says the 508 is designed for 125 - 250 watts per channel. I would like to think that 75 WPC would be enough to listen to them at reasonable levels. https://www.hifi-classic.net/review/altec-lansing-508a-96.html

    SX-680 power switch repair or replace?

    I found this on eBay as an example of a 680 switch. Assuming that it is, you would have to drill out the rivets to get to the switch. I can't tell what's going on what's going on inside the metal bracket but it looks kind of like this type of switch. Not sure how the push button actuates the...

    Say it isn't So! Technics 1600 MK2

    I also tried to send it via messages. The 3 service manuals on VE are 12.8, 3.6, and 2.9 MB which are all too large.

    Need help with a CA-800

    I have a Fisher CA800 that the power meter acted that way when I got it. It had a blown STK0080 power pack.

    cell phones at concerts, yay or nay?

    I'm a resounding NO. I can't believe anyone goes back and watches it again?? I was at a concert and there was a lady recording some part of the concert and she had the flashlight led on! Thankfully that didn't go on too long. I'm not sure if it was a mistake or she thought it was helping...

    Dual-C Filter Capacitor G-7000

    If maintaining the old appearance isn't a priority look at adapt-a-cap for a pcb board that allows up to 4 new caps to be mounted together.

    Dual-C Filter Capacitor G-7000

    I used this method detailed in the thread below. It's really more for the type of multi-section cap you'd find in tube gear. It worked really well. I heated the exterior of the cap to help the guts slide out more easily. I always like to maintain the look of the old cap but that shrink wrap...
