I've been so busy with other things this project got put on hold and I haven't been able to pick it back up yet. I know it's been over a year and it's been bothering me that I haven't been able to finish this. I will complete this project as soon as possible.
Just picked up this amp tonight for a song and a dance.
Not sure what to expect.
I quickly checked both channels in my garage and they seem to be working
Curious to how this might compare to my Yamaha M-4 Power amps.
I will try to audition it tomorrow.
Does anybody have a service manual for...
After drying for 24 hours there does not seem to be a huge difference between the surround sealants.
The stuff from Roy remains very wet and sticky. It would definitely have no problem soaking into a woofer.
The stuff from eBay is still very sticky but not wet.
The original surround on the...
So i have been living under a rock for awhile and have no idea what kind of options are out there for this today.
I have been using Pandora for years now and love how it is able to find and introduce me to new music that is similar or relative to what i already like.
I was born in 89, Lots of...
I added glue between the magnet and front/rear plates to prevent potential magnet shift.
There are a few reasons i decided to use the clear gorilla glue instead of epoxy.
I have 12 drivers to glue and epoxy hardens very quickly, I prefer to take it slow and do a good job. Rather than rush or...
The surround sealant I ordered from Roy-C arrived quickly, but the stuff I found on eBay took awhile.
Tonight I put some of each onto a piece of toilet paper to see what it is like when dried.
The stuff I bought from Roy smells a lot like rubber cement.
The stuff I bought on eBay resembles...
found this product: eBay item number: 290600563656
According to the description it sounds like what I need.
I went ahead and ordered it.
Shipping is going to slow down my progress a few days.
I will wait and do it right.
I fear that if I put them back together and start listening I might not...
While working on one of the woofers I decided to pump the breaks and report in before I continue any further. If I shine a flashlight from behind the surround I can see lots of light passing through. Do these cloth surrounds need to be re-doped?
If so.. what should I use?
I did not want to...
Tonight I made progress cleaning the drivers. using Acetone (fingernail polish remover) made it easy to soften and remove the glue that held the mesh grills in place.
I used small paint brushes, and Q-tips with a bit of water and dish soap to clean the midrange and tweeters on the first pair...
I made progress yesterday and now the crossovers are nearly complete.
I am going to swap out all the old 18AWG wire and use some 14AWG silver plated copper PTFE wire.
But before I do, I need to clean the drivers.
There is a thick brown layer of dust sitting on top of the drivers.
These were...
I Noticed that the serial numbers are dramatically different on my pairs. one pair is SN-15914 and the the newer pair is SN-63937
So tested the older crossover and found values even higher.
94uF is reading 128.4 uF
21uF is reading 25.8 uF
3.5uf is reading 4.3uF
2.7uF is reading 3.3uF
Because...
I tested the values of the original capacitors and every value is reading high. I have three different capacitance meters and all three are giving me consistent results.
94uF value is reading 115-119uF 26.5% High
21uF value is reading 24-25uF 19% High
3.5uF value...
