meters

I have a thread elsewhere in this section about my SX-680 adventures, but this is somewhat more specific, so I figured that a new thread would be a OK. Here's the quick version of the issue: When I turn on the SX-680 with the speakers connected but OFF the meters on the front panel ocellate a...

Hello AK. I recently bought my dream amp, a CA2000. Sadly one of the meters appears to be cooked. It's such -20db and doesn't move at all. I tried to loosen the screw a little and tap the needle to see it woukd move but it seems pretty well sad. Also, the screw seems way more brown (burned...

Hi everyone. I have a Marantz 300DC with a Marantz 2245 serving as the pre-amp. The 300DC is hooked up to a pair of JBL 240Ti's which are 8 Ohm with 89 dB sensitivity. With the gain knobs turned at the half-way points (12 o'clock) and the -20 dB meter range button pushed, the power meters are...

I picked up a very handsome Pioneer SX-790 (the dark-dial equivalent of the SX-780) and had to replace bulbs and clean it up a bit. (As you can see, I'm experimenting with some ice blue LEDs.). Odd thing is: the meters sometimes dance even when there's no input attached (PHONO or AUX -- not even...

My Sansui 7070 was purchased used from a few years back. I didn't really take note of the colors of the meters, they are green (for the radios) and blue/purple (VU). But I saw a few photos of the x0x0 series from the web, and noticed that none looked like mine. May I know are these likely to...

Good morning race fans! Relative newbie looking for some input on a DIY bench power monitoring station... I have been working on tube gear for a year or so and the variac is a great tool. I have a 15A staco unit that weighs enough to use it for home defense. I also put together a DIY AC meter...

Hello everyone. My sister found an SA-725 receiver than is in wonderful condition! All inputs work, no knobs crackle, phono EQ is good, lamps work - everything but the tuning meters. I opened her up and the inside was clean. I mean very clean. I tried the tricks I'd read elsewhere: loosen...

One day the left channel Output Level meter on my C2300 indicates 20 dB lower output than the right channel, but the actual level is still the same from the left and right channels. This is regardless of input selected, mono activated or not, any output used, balanced or not, and swapping left...

I am contemplating picking up a nice 2205 amplifier for my son, nice cosmetic condition from a trusted source but non working meters. The lights work but the meters don’t move. Any ideas how costly a repair of the meters might be? Thank you, Gary

I found the intermittent contact on my (new to me) MC2155. It was on one of the harnesses at the front of the amp. I tightened up the contact for that pin (on the harness) and it's 100% percent functional in both channels. Now....the bad news. There was a flickering LED in the rightward most...

Hello ! As the title says, what will be your preference? Different sound? Is there a difference between these two models? I know both models have exactly the same hardware (or maybe not, it's why i'm asking this question!) Also, there is some push buttons for the meters on the Marantz 300DC ...
