vince i too am in the process of building the blab buster. i have 2 posts below (tv man) with many replies that may be of interest to you. one was how to fabricate the 1uh choke. i bought the magnet wire at the shack. i was going to leave the connectors off and hardwire my audio in and out cables di...

if the "crystal" is an orange ceramic resonator i'd say 50/50.
i have replaced them in tvs and remote controls. only the freq was differant.

mr.EDD :&gt ;) i would think the resulting board would look factory made. but i am going to try the trace,resist pen way first. if it doesn't turn out well, then i'll go the way you just described.<p> anyone curious as to what the the project is and what the circuit trace looks like, go check th...

mr al
the same 1 uh as in my first post :&gt .

thanks dean.
my pc board needs are small.
so i am better off using the trace,resist ink method as described in earlier posts.
also my wife thinks i have too many goodies as it is. however using my junk to repair something of hers doesn't count.

even in my retirement i repair an old modular zenith syst 3 now and then. one of the resisters that frequently goes bad(it opens)is a 2.7meg 1/2 watter. using this i wont worry about lowering the coils Q. the project i'm building is the "blab buster" that was in the feb issue of N&V. t...

thanks ED
exactly what i was looking for. and i have a few high resistance,half watt carbon comp res left over from the old days.

i checked the shelves at the shack and couldn't find none.
so i need instructions on how to wind a couple of 1uh choke for my project.i suspect i'll need to wind the wire on a high value resistor. so what gauge and how many turns do i need?

i want to thank every who posted a response to my query on making a pc board. it comes back to me after reading all the advice. i guess i was hoping not to sit for hours tracing the pattern by hand on the blank. i wish when nuts and volts has a project, the list of parts would have a source of a boa...

i must be getting old and forgetfull. i need info on how to make a PC board from a blank that i can then etch w/my radio shack pc kit.
a web page with tutorial would be fine

i have my chip.to all that replied via e-mail and here i say thank you.
now all i have to do is etch the board.
anyone else out there actually
building this project?
i am going to insert the finished project before my old tube amp to try and tame my dvd/cd collection.

i am waiting to hear from anyone who has built the project. i am hoping there were no errors and i will wait for the next issue of N&V to see if there is any feedback concerning the project.<p> to the kind person that E-Mailed me privately i am waiting for your reply to the letter i sent you.

i am looking for a source for the NE 570 used for the "blab buster" in the feb issue of N&V.
a source of a complete kit would be even better.
