Speakers / Re: Speaker kit experiments
« Last post by Doc B. on Yesterday at 06:03:33 pm »
Went a little off the deep end the past couple of days playing with a potentially silly idea for the diffraction felt we will put on either side of the kit speaker tweeters. Have no clue if it will work better, worse, or just the same as a strip of felt or shark's teeth shapes like most everyone else tries. Anyway, I like the look. After 9 hours working out a quadratic residue diffusor cell layout that would fit and function at the frequencies of interest and getting the shapes into the CAD software yesterday, the actual cutting of the pieces took just a few minutes. After a few hours of swearing at the laser cutter software today, that is. At least with my past CNC experience I knew that was coming. Will be comparing these against straight strips of similar felt tomorrow.

I actually only picked that when I saw the small speedball boards.

I like my Weller soldering station.  I got a third hand, but haven't used it much on my Bottlehead projects.  I usually make a mechanical connection before soldering, so the third hand doesn't seem that helpful to me.  It can be more useful if you plan to make your own interconnect cables though.

Seductor / Re: 6P15P for Seductor?

The 6p15p is not a direct EL84/6BQ5 replacement, so without modifications, I doubt it.

6p14p is the Russian EL84 equivalent, as supplied by BH in some kits.

I strongly recommend Chemtronics Chem-wik solder wick and a Hakko solder pump. They made desoldering so much easier (when installing and troubleshooting the Speedball).

General Discussion / Re: Blowing fuses in PP amp
« Last post by vladimirwolfe on Yesterday at 02:18:54 pm »
Paul & Doc,

Thanks for the replies and I apologize for taking so long getting back. Life gets in the way and I do have another system so it wasn't absolutely imperative to get this running right away.

Paul, I tried removing all the tubes (rectification is SS) and the fuse still blows on startup.

Doc, I did have some crackles and pops and I cleaned and "squeezed" the power tube sockets and the problem went away. This was about 2 weeks before the problem.

I did talk with Mike Sanders at Quicksilver and he recommended checking the diode bridge and the main power supply cap...
I'm trying to avoid having to ship these heavy beasts but am nearing the limits of my skills.

Crack / Overkill for my first Crack and speedball build?

Weller wes51 soldering station
Kester 63/37 .031 solder 1oz
Quadhands 3rd hand soldering tool and vise
Desoldering wick 5'

These items are all in my amazon cart, but I wonder if I'm overthinking it?

I'm a Honda technician, so I have a good dmm and the tools covered, but I have a giant Snap-on soldering gun and only ever solder 2 wires together. This will be my first small soldering job, but I really don't think it will be the last kit I build, so I'd rather have the soldering items covered and future proof. 

Opinions welcome!

hey thanks. for venting the plate sits about an 1/8" over the base on small rubber feet - i also like the look of the relief between the two materials so it serves two purposes. it's easy to take off as needed. attached is a snap of the back ...
