fuse

I recently was able to buy a Sytemdek IIX that appears to be an early model (steel bottom, teardrop armboard). When the power switch was clicked on nothing would happen. I researched a bit and thought it would be the capacitor but ultimately turned out to be the switch that was faulty. I've...

I have been using a Magnavox 9303 tube amp fed by a Marantz 2230 preamp for the last 15 years. Love it. Suddenly there is no sound. I can even tap the bare input cables and there's no hum--it always hums slightly--and no touch response, nothing. At first I thought it was the fuse, but the tubes...

Hi everyone, I came across this forum, looking for some expertise on my broken RX-530, which I saved from my dad in order to fix it up. It's a childhood memory device for me, so I don't care too much if it's worth the effort in the end. To the problem: I found the device has its main fuse on...

I’ve had my 9090 for a long time - and I had a terrific AK member CDfixer restore and upgrade mine (RIP CDfixer, he was a true gent and I’m very lucky to have met him). One thing that I’ve noted is that my unit has the updated fuses (pic shows two 10a fuses). A few questions: should I change...

Looked a bit rough, but local and for beer money I went for it, have to save some. Anyway I get it, open it up, blown fuse. New fuse and we have music. Today I decided to check it out again. Make s list of some parts, for a "restoration", so was detailing the back a bit. Took the fuse cover off...

I bought a pair of Advent maestros today. The lows and mids were beautiful but the highs were somewhat muddied. They’ve been refurbed, the foam on the front is beautiful and the speakers in general are in good condition. I brought em home and left them, I had to go to work and was gonna set...

Hi all! Long time lurker, first time poster here. I recently got a pretty worn Marantz 2015 (with wood case) for 50$. Main fuse (on the back) keeps blowing on power-up. I found that the output transistors were blown, so went ahead and replaced those to no avail. Still getting blown fuses. Any...

I recently bought a pair of Technics SB-X30 and am having some issues getting them to work properly. The issues I am having mostly have to do with a these so-called "Speaker Protector reset buttons" on the backplate of the speakers. IMG_20221208_230213 by NickHam1122 posted Dec 9, 2022 at 9:48...

Good news! I stumbled upon a Realistic STA78 at the local GoodWill and nabbed it for a steal. About a week later found some Marantz Imperial 6s at the same exact place. Figured this could possibly make a great little system. Now for the bad...It has loud static out of the left channel. Before...

I have a SAE 5000 that is missing its fuse holder cover. I just got one from a seller on ebay, but I don't know what size fuse to use. I've looked for the service manual and was only able to find a manual for the 5000A, which apparently doesn't have an external fuse and makes no reference to...

I bought this stereo at a thrift store for $15 about 6 months ago and have been using with some old speakers that I also thrifted. We really like the sound of it and my girlfriend and I have been trying to learn a bit about it. I guess we are noobs to the audiophile world. I thought the volume...

Greetings Is there a fuse that affects the power light only on this unit? I can’t find a blown fuse anywhere. The power light went out on my rtu11 this also seemed to affect the lights on my tau11 vu meter lights. When I hook up the tau11 to a different rtu11, one where the power light works...

I have a Hafler 9270 Power Amplifier. It had recently blown a fuse due to an external short. The manual just says to replace it with a 7amp fuse. The blown fuse says the following: 250V 3/2 (or 312 wasn't clear) 7A. It does not specify time delay or any other type. Which one should I use?

A fellow gave me is subject amp today for free. He only said it does not work and that he changed the fuses. Upon inspection: - the switch in back was in mono-bridged position, so perhaps why he thought broken - the fuse in the AC fuse holder is a 20A fuse, way above the 12A spec. Two...

I got this great amp in after an extensive repair/refurb. The refurb was valid only the amp returned with the complaint "blown fuses". Indeed, the fuses in the line for the power output (2x 6.3AT) had failed. Could not find anything amiss but upon returning the amp the fuses were found to be...

There is a a 68 ohms 60mA fuse resistor found in the Yamaha A-1 and other Yamaha amps of the same period. Could anyone tell me what is the best substitute?

Greetings, A very close friend from high school convinced me to go the Hafler route many years back and I purchased both a DH-110 preamps and XL-280 (both in kit form) just about 35 years back. Though I've had a few minor connectivity issues arise over the past few years with the DH-110, the...

Visited lady in her garage with equipment for sale. She plugged in M50 amp via extension cord. Protection light came on & went off. We started chatting about other stuff & maybe ten minutes passed - smoke out of amp. I know better and should have gone right into wall with cord. What I am I up...

Hello, I'm new to the forum and hoping someone can help. There two issues with my Marantz 2230 (thrift store find). So far I've replaced all lamps with leds, replaced the tuner cord and fixed one of each of a cap, resist, and rf coil. I also cleaned all boards with air and 99% alcohol. Before...

Greetings stereo experts! I am having a few issues with my Nikko STA 5010. The right channel is the issue and can be sporadic at best. Normally toggling the input selector would reengage the right channel, along with reseting the fuse at times. I am now getting nothing and the fuse just clicks...

While trying to remove the 8v fuse lamps on my HarmanKardon 730 twin power i touched both sides with the pliers. Should have never been on. Unfortunately the lamps that were on, like the pointer and one behind the dial, went off. After installing the new bulbs behind the dial none of the lamps...

All but one of my lights was working. I swapped the non-working bulb with one of the working bulbs to test it out, now none of the bulbs are working (except the FM STEREO light). Can someone kindly direct me toward the fuse for the lights? I was thinking it was F04 but it seems to be okay. I...

I came across these speakers at an estate sale, nabbed them for $225. I was listening to them attached to a Pioneer SX-850, but have since decided to move them to my home theatre system. When I plugged them in I noticed that one of the speaker's fuses was missing. The speaker still seems to work...

Hey friends, it's been a long time, but I'm finally back to servicing and maintaining my gear. My Marantz 2240 blows a fuse every time I power it on. Can you give me some advice on where to start looking for issues? I'm attaching a few pics and the schematics. This sucker is very clean with no...
