Go Up Go Down
After coming down from how nice it looked I realized "damn" he's right I gotta redo this turkey.  I have a new prescription for one falls more into line.

Diameter = 11"/280mm
Turns = 26
Guage = 20 AWG
Induct. = 376 uH
DC Res. = .77 Ohms

Now I just have to finish drilling my boards and get them populated, the case is ready for the them. Then rewind the coil, make battery & coil hook-ups and I'll be ready for tune & test.

P1,P2,P3= 25 K Ohm . A few other DBP-2010 construction tips are mentioned earlier .

Hello Line .  Sorry , I have no extra parts I can sell . Delta pulse parts can be purchased in your country . The best way to purchase PCB "Circuit boards" are to order them in very large quantities to keep the price very affordable , this must be done in order to offset the high price of over-seas shipping !! There is not enough demand at this time for large quantities because it's summertime . But it is something that can definitely be discussed in the late fall or Winter .

You may want to ask other members in your location if they are interested in getting some boards made sooner .

HH.............Eugene

vdubber,

Set P1 & 2 at about 11 o'clock and P3 at 12, that's where Xavier suggested I put mine.  That's for single turn trimpots, experience says don't use multiturn pots keeping track of how many turns this way or that is a bummer.

Hello . Is the DC resistance posted above at 0.77 ohms correct ? I thought my notes said around 1.9 DC ohms resistance on the DBP-2010 search-coil !! I better re-check ?
