[kt315]

check the transistors again and check pinplacement of them at first. this part has to work good and
i checked its work by o-scope much years long ago. first were russians who told about how DP working.

OK

I am done with these PCB assemblies, no success after many trial and errors.

Considering buying eBay assembly: https://www.ebay.com/itm/Sniffer-XR-...-/333068183754

This may be from a member on here - Any other suggestions?

If I buy the assembly I can focus on coil construction and tuning and work my way up to building PCB after that

I would like to stick with Delta Pulse for depth reasons. I am after ship wrecks covered in sand in shallow water. Need to find wreck sites with big detector and then go in with VLF detector for coins and good items

Only problem with the pre-assembled boards is have they been tested to see if they work before shipping to customer. If you can have confidence that they have been checked, then its OK. Contact seller first..
