Good day AK members! I got this little Pioneer SA540 amp for cheap as not working. After some time inspecting it I found that speaker terminals have to be replaced (damaged, not working anymore). Did give this unit a good cleaning inside and outside. I have also replaced speaker terminals. The...
I just blew my two 2 x 4 smithline speaker fuses and need to replace them but don't know where to find them. The smithline contact phone number is a wrong number at this point. It looks like a fast blow thin wire fuse about 1 1/4 inches long.
I wanted to replace the fuses in my b2 with "audio grade fuses", ya ya pelt me with rocks... the ones that are in there are normal acting the board says T500ma and from what I can gather that is Time Delay but I really don't want to mess anything up. Also has 2 5A fuses they don't specify on...
I purchased a pair of Dahlquist DQ-10 that were supposed to work perfectly, but didn't. By the time I found out I had driven 3 hours to get them (6 hours total).
Woofers dry rotten and some of the drivers weren't working at all.
I replaced the foams using Rick Cobb's kit, checked all of the...
B77 fuse blew while fast forwarding It is a 5x20 1500ma 250v slow burn. Is that the right fuse for the USA?
And where do you buy them? I tried car shops and Lowes and they didn't have any.
Thanks
I have a G-7500 running a pair of Ditton 44 speakers and it sounds fantastic! I purchased the G-7500 about 6 months ago and it has be working great with daily use. Last weekend I decided to detox the switches and potentiometer's as they were overdue for a cleaning. The first thing I noticed...
Hello,
I was changing the TIP47 on my akai gx-620 (power off) But when i wanted to use the multimeter with power on, I accidentally had the power switch come into contact with the housing. Then everything fell silent and the T5 fuse blown. I inserted new ones and every time I power it, it burns...
HI All,
Very new here and wondering if someone can help out, I bought a Marantz 1090, and it keeps blowing fuses in the position shown in pic and circled in red. What size are these suppose to be for a 240V in the 2 positions ??
Also if they keep blowing, any guidance on fault finding would...
Hello AK-members,
I just purchased a JVC A-X2 for 20 euro. Thought I give it a shot as I am looking for an amp with more power than my current one. Hooked it up to my speaker and the disappointment came: no sound. Well, just extremely soft.
What I found out:
- The relays click after some...
I am in the process of recapping a Sansui AU 7900. It works fine, but it was pretty beat up. Not sure if the sound is as expected plus there is also a cold solder somewhere in the main board. So thought I'd replace the usual prone to fail components (Caps, VD1212, fuse resistors) with new ones...
I am considering placing 2.5 to 4 amp fast blow inline on my Fisher RS-Z1 receivers speaker output.150 watt ch @ 4 ohm. The speakers are B&W DM640i rated at 200 watts / 4 ohm. This would be a small insurance policy in case some unknown issue arises with speaker drivers to protect amplifier. Has...
Hi,
Got an old Audio Dynamics C-200 surround preamplifier. The lights don't work but the preamp itself is still working. Could it be a fuse? Not one is lit.
Any suggestions?
Thanks

A friend of mine have an Akai AA-1020 with no left channel output. We found out that blown fuse could cause that and decided to order all of them since I'm already placing an order on Mouser. However, while looking at the Service Manual, I'm not able to determine if the fuses are fast blow or...
Hello -
I just acquired a ($20) 331 that was known to blow a fuse.
Upon inspection, F604 was blown. I replaced and it failed dim bulb test.
I then replaced C603 and C609 on questionable visual inspection - it seemed to pass DBT (albeit the bulb flickered in a strange way)
So, I brought it up...
After recapping and replacing many transistors, diodes and relays on Sansui G-9000 and Marantz 2275, I feel comfortable enough to tackle the C-4.
It worked fine and then it started burning fuses immediately on turn on.
I read http://audiokarma.org/forums/index.php?threads/yamaha-c-4-help.361407/...
What is the correct size please? I bought a pair from an auction. The crossover needed some heat to reattach things. One speaker has a fuse marked 250V/7A, the other has a bent box staple. The one reference place I found was confusing and suggested a much larger fuse than 7A. The specs...
I uncovered a Technics SL-1400 (original, not a MKII) in a garage recently and was hoping to get it working again. It's pretty dingy but can be cleaned and nothing looks broken. When I first plugged it in and started the platter (by moving the tonearm) the platter spun really fast although it...
Hey guys!
I'm helping a friend repairing his beautiful Denon DP-80.
About a week ago, he turned it on without using the step-down transformer; so our denon got a 220V charge instead of a 100V. The plate spinned a few seconds then stopped.
The 1.6A 30mm fuse was blown, we tried to swap it with...
Hi guys,
A friend of mine recently brought me this integrated amp. It was about to be thrown out by the owner of a local bar, because both channels cut out one after the other.
So I took it upon myself to try and safe this nicotine brown workhorse.
Initial testing with headphones revealed...
Might anyone know where I can buy or replace fuse and fuse caps for a Dynaco Stereo 400? Any help or points in the right direction are greatly appreciated.
Attached is the current fuse/cap that needs to be matched.
Hi guys,
I've been trying to trouble shoot my Marantz PM7200 amp with the help of member MBZ (he's been AWESOME). Well I stuffed up and slipped while testing the emitter of a transistor with an oscilloscope. Yea I slipped and shorted it out with some minor sparks. I removed ASAP and turned the...
Now to start this off, I don't even know if this is the right place to put this since my JVC isn't exactly "vintage". It's from 1993 and actually looks newer, so I honestly don't know. Second, I'm new here...as you can probably tell. Alright, now on to my problem. So a while ago my poor JVC was...
Hello. Sorry if this is s novice question. I recently acquired a Dual CR 60 receiver, in what appears to be very good condition. It’s currently set for 220V, and I need to change it to 110V to function in the U.S. I know this is done by switching two fuses. Unfortunately, I damaged the fuses...
Hello everyone,
I have a pair of old cabinets from the thread title, and I noticed change in loudness on one of them. Closer exam pointed to circuit breaker that has increased resistance. So I guess I need a new one... I tried searching for the original part but, for now, I had no luck.
I know...
Hi all. Pardon my incredible ignorance here. My understanding of electronics is as basic as it gets.
The lights and FM signal strength meter do not function, and I suspect that it has to do with the internal fuse (not the speaker fuses on the back of the unit). The text next to the fuse says...
