Having gone through everything I can find on this site about the Delta Pulse, I can say with certainty there is no clear explanation for its construction and stage testing.
Many videos and links have over time been deleted or no longer connect to anything.
Having never built a detector I have read extensively about them. I can fix most vintage hifi equipment given that a relevant manual exists.
That said the Shangling SCD T200 looks and is said to sound amazing but there is probably only one person in the world who can fix them
and he won't because they are hell to work on added to that key parts are of the unobtainable variety
Problems in vintage hifi most often are electrolytic capacitors in the power supply, rarely do I need to use an
oscilloscope, & I have not touch one for the last five years. I have all the test equipment but no one really shows where the leads go when testing.
You see a video or picture of an oscope image but where are the leads going? I suspect flyback is measured off leg 6 of LF357 and + Earth
or is the +E, but find me a picture of that. Maybe its pin 3, what is pin three? how do I count the pins?
What happends if you slip with a lead when the power supply is on?
If its a component connected to a heat sink its likely bad news.
I did that once on a Philiphs CD104 and learnt alot about diodes.
So what is the purpose and what am I going to do.
Post images and comments which I hope fill in the gaps of building a metal detector.
Frequency, pulse, band width, waste line all these terms I find a bit of a head banger.
Maybe I should put together a glossary of terms, probably not a good idea although I know what an expanding waste line means.
Maybe a proper glossary that could be incorparated into and introductory book for beginners?
Well must get back to work
PS
