power switch

Hi all. I see people often talk about the volume pot/switch on this and similar units, but usually regarding volume issues. Just got a non-working MX113. My issue is that the unit will not turn on at all when turning the knob. I briefly bypassed the switch and the unit lit up like a Christmas...

Hi, newbie here- Thanks in advance for your help. I have an early C31V with the volume buttons (Serial ER1041). It's been poorly stored in a box in a shed, but otherwise undisturbed for years. PROBLEM: Plug it in, press red Power button, it wont turn on. Totally dead. No clicking, no lights...

Hi all! I'll try to keep this to the point. I'm replacing an ALPS toggle power switch in a Sony STR-6055. The old switch (which broke in shipping) had a snubber (or I've heard some call them arc suppressor networks) soldered onto two of the switch contacts. The component is orange, branded...

I have a Conrad Johnson PV2 whose power switch is stuck in the "on" position. I'd like to replace it rather than continue with it plugged into a power strip to turn it on and off. Conrad Johnson just told me they don't sell parts. They said they'd replace it for the price of the part plus...

I have a 2226B needing a new power switch as the original is arcing badly. Would anyone be able to confirm an appropriate replacement for this switch?

I know that replacement switches for Marantz's can be ordered for not much money, and this is my backup plan. I recently acquired a 2270 with the common faulty switch problem and am replacing it. I went to a local electrical supply store that has a good selection of switches and located a...

I need a Power switch for an SX-980. I've seen in many forum posts that power switches for 939, 1010, 950, 1050, 1080 1250, 1280 will work. However, I located a switch supposedly from an SX-939 and it is labelled ASK-067 instead of the ASK-080 from the SX-980. Can anybody confirm if the ASK-067...

This 2250B has an issue with the power switch that it won't stay engaged. Measuring resistance across the current connections indeed show the pads must be really worn out. Instead of swapping it out, I just connected them to the other side and that seems to work. Just wanted to ask and make sure...

HI, I have dozens and dozens of switches laying around of all different ratings and I was wondering what the ideal rating would be for voltage/amps for a on off power switch for a marantz model 32 power amplifier. Thanks

I got this 3600 in working condition (but in need of a recap). It came with a badly burned power switch which may have been caused by a short on one of the unswitched outputs (from the looks of it). What switch could I use to replace it?

I just got a Denon PMA 737 integrated amp in fair cosmetic shape for $9 at the Goodwill that will not power on. They were kind enough to take $4 off the price for that reason. I bought it thinking I wouldn’t end up chasing the chicken repairing circuits cuz no fuses were blown, and I’d end up...

Hello Everyone! I'm relatively new to vintage audio but the love is strong with my Pioneer SX-750 from 1977. I started doing a recap on it after numerous hours of research not to do wrong. The power supply and protection board AWR-099 is done, it went smooth, I'm currently waiting for all the...

Hello good people, I'm having an issue with an arcing power switch in my Philips 22-AH-686 receiver. I thought initially that I had dirty switches / pots but a thorough cleaning did nothing to help. I am fairly sure that the problem is the power switch. I will also test the output transistors...

I replaced the power switch and it all turns on and works, except the right side speakers (main and remote) it isn't the speaker cuz I tested the speaker on the left side and it works. Both channels worked before replacing the power switch. Any ideas? Are they related? Fixes? Thanks!

I recently removed the Omron power switch from my Sony 7066 Receiver b/c it was malfunctioning and discovered it was cracked. It's a small plunger type switch w/ three prongs. The numbers on it are V15-1a, underneath this is TV-4. Top right corner has 295 3R4 written on it. I have not been able...

My main bedroom stereo is a beautiful 1983 Pioneer SX-50. It sounds incredible, with 50 WPC at 0.007% THD. The only problem with this unit is that it seems to have a dirty power switch, and this problem only occurs when the stereo is "cold", being turned on after a few hours, or the next day...

Hi all. I purchased a kenwood kr 6050 a few months back and have been cleaning and working on it myself. I recently replaced the lamps. Pretty strait forward and easy. I've also had to clean the contacts in the power switch. It was arching pretty badly when I first purchased it. I've done so...

The power switch does not work anymore, and I think while it's not completely FOOBAR, after the repair I would not trust it to still work fine in a few years... it has a very flimsy construction. I think this is a very common issue with these switches, this is the second B2 I lay my hands on...

Hi, I recently acquired this unit. Technically the amp board is the same design as model 3020 with a tuner added. It's got a couple of issues. When I initially plugged it in I heard a gargling sound coming from the transformer and later a thin line of smoke ;-) I narrowed the problem down to...

I have a KT-7500 and have had it sitting in my study for about 7 years. It was part of a deal to buy a Model 600. Now I've sold my Model 600 (not working) to an AK subscriber who is bringing it back to life. The replacement is a nice KA-7300 that will be delivered on Wednesday. My thought was to...

I have a Marantz SR 4000 and the power switch had gotten stuck in the ON position. After much lube and tinkering I figured I may as well save the money, take the switch apart and clean it up. (These are not built to be taken apart) Anyhow I can't reassemble this switch. Looking on...

I recently got a TU-9500 in for repair that had a problem with constantly flickering lamps, turns out the power switch was the cause, it would measure between 1K ohms to 15K ohms in the closed position. The power switch is an interesting setup, the toggle actuates a basic plunger style switch...

Is there a preferred brand or config for a 2240 power switch. Ready to buy and my main concern is shaft length and fastener screw spacing...many on Ebay promise exact fit but many also do not look the same...I would like to get the same throw length and feel as the origial..and can anyone...

Getting around to finishing up some issues on some of my older gear collecting dust. The power switch on my Realistic STA-82 does not stay engaged in the on position. After about 3 seconds it pops off. Holding it in with a finger keeps the unit on. I'd appreciate any ideas for a replacement...

After restoring a Teac A-6300 for a customer I powered it up for calibration while listening to my AM radio. Whenever I raised the auto shut-off lever to thread up a tape I heard a "frying" noise come out of the radio's speaker. When I released the lever the noise stopped. Simple reasoning...
