Ouch, I think you can use your de-soldering tool and remove it.
Good luck

IF all Fail, build this instead:

That was my reference.

I'll give it a shot tomorrow.
Fingers crossed.

Mariusz,
It has been my experience that for a multipin component Solder Wick (they should have this at Radio Shack) has worked best. Luckily in this case you can use plenty of heat because this is not an active component that will burn up, but still be careful as you don't want to lift the paths off the board.

Good Luck!
Ed

Mariusz if you have any problems getting it out you can always send it to me and I'll take care of it for you. I do have the way and the experience to do it without issues.
Gary

Thanks everyone.
I'll give it a shot later today
& report back.

PS

I'll be building my own enclousures (this buffer, Class D amp and another buffer-recasing) made out of Maple - except top and bottom.
I came across this company who sells mirror like finish aluminium & steel sheets/plates but forgot to bookmark the page. Now I can't find it for crap.
Anyone got a source ?

Thanks, got this one just in case but I do not think they have what I need.
Nice stuff tho. OK prices.

The sheets I was looking at were just like mirror. Used for interiors, boats, RVs, custom bikes etc.

They sell by sheets but do send samples of 12"x12" cheap.
I think, next size was 12"by24"???? Not sure if they do custom sizes????

You can use one of my cases and put the Class D and the Buffer inside. I think it would work. Just a thought...

The link I gave sells any size with no minimum order. They cut to the size that you request. Just put in the size you need.

I know they do but not sure if they have that "Mirror like" finish?

Jtwrace
thanks for the offer
your cases look very practical and easy to work with but making it easy is not my thing....... I'm polish.

I would have take you on you offer but Ill go with wood to match the rest of my gear/deco.

Hey guys, I'm listening to my buffer!

My son had a wrestling meet in Franklin IN this weekend, this required an overnght stay. I figured while he and his buddies were messing around after the meet I would work on my buffer at the hotel. I had already soldered everything (so I thought, more later) and had modded my case to be able to mount the RCA's etc. So I was able to finish my wiring of the buffer in about 3 hours Sat. night, most of that time was making up my mind how to route the wiring. Once I arrived home I put my battery in the case, installed the fuse and tube, connected my RCAs and powered up. Surprise! It all worked, first try! The remote worked and everything was playing, the problem was I had very noticable distortion. I called Gary and he thought it might be the tube. I had a couple of other tubes available but no luck, the distortion was still there. I called Gary again and he recommended trying another amp, again no change. I then remembered that I meant to look into the reason I had two diodes left, so I started looking around in the amp and sure enough I found two diode locations empty on the remote control reciever board right in front of the relays, I looked at Gary's instructions to verify where they were suppose to be installed and there they were. I installed the two diodes and VIOLA, clean music! I am very happy with it although it is much too early to offer feedback on the sound.

The remote works great (although I will refrain from licking it

).

I went ahead and built the buffer into my unfinished case, I did this because I have a large speaker project I am in the middle of and I didn't want to wait to hear the buffer. I will be finishing the case once I have the speakers completed. I have built the buffer so that I can easily take out all of the componenets without having to unsolder anything (I was not able to solder the fuse case, everything else is soldered).

I found Gary's instructions to be excellent and had no trouble putting this together.

Anyway, here are a few pics!

Best,
Ed

Cool Ed.
Hope to finish (use) my by next tue.
Trying to figure out the way to rise the potted tube socket so the tube itself would be accessible from the top without removing the cover?????

How does it sound so far????
Nice case won't make it sound better.
So...., how is it?

gld · « **Reply #273 on:** 26 Apr 2010, 06:55 pm »

Ed That's great!!!

1st one done and it works WOOHOOO.
Let us all know how it sounds.

Too early to offer much feedback other than it sounds really good right now. I am using this with my Class D amp, they will look basically the same when finished.

I can't offer much more than that becasuse I am presently listenig to music from 200Hz up, I am building Danny's V-1s and I am only listening to the coaxs, so no bass.

I hope to finish the speakers in the next couple of weeks.

Best,
Ed

Got it.
Hope your speakers project works out as smooth as this one.

I can tell you I am listening to Shelby Lynn's "Rainy Night In Georgia" and she has never sounded better on my system

. I can't wait to get this system back together!

Best,
Ed

Mariusz, I considered this as well. The solution I came up with although I decided not to implement was to mount a bracket to the lid that would bend down and under the tube block then back up to the lid. You could probably do this from the bottom of the case as well, that may work better. I was going to use some 1" wide aluminum bar stock that I have. Of couse only about half the tube would penetrate the top but that should be enough to make changing tubes without rmoving the lid doable.

Best,
Ed

Dodd buffer rules

Good ideal to keep the battery inside the chassis.

Yes Gary, how about that! Your instructions are so good that I wouldn't hesitate recommending this kit to anyone who knows which end of the soldering iron gets hot!

This thing is fresh but I can tell already that I like what I am hearing, especially Shelby Lynn's voice.

More as this thing breaks in and I have some full range speakers connected.

Best,
Ed
