Inca Tech Claymore Mods and Repair Thread
Starter thread for Claymore 1 Repairs and Mods
I am starting this because I can't find a central repository for all the mods, upgrades and repair advice that can or need to be done on the Claymore 1
maybe keep this thread just for the Claymore 1 and start seperate threads for other versions?
maybe different threads for different boards issues?
Schematics online..to save Colin PM'ing them all the time unless he wants to keep it that way? Copyright etc Colin?
Annotated photos of the boards for the less tech inclined so we ( I ) can identify parts / test points for fault finding etc.
What voltage shoudl be were on a normal system etc..to aid in finding probelsm
list of mods I have found so far :
Replace caps for bigger..15,000μF especially if the old ones have started to bulge and leak
Op-amps..fit gold plated sockets and replace with newer types
Change volume pot to ALPS types
Replace internal wiring
Replace or remove and hard wire the Lucas style crimp connectors with hard wiring
Wiring Pre-out sockets to the two spare back plane holes..where to take the taps from.
Replacement of MOSFETs what is now available
Setting Bias current. "How to..." needed..
Selector switch...source for a better quality one?..I have had to replace mine twice now in the 25 years I have owned mine.
Replaced with RS Cmponents Lorlin wafer switch..looks like original RS p/N 665-196
Adding another input. The front wafer switch is a 2pole 6 way, but since only 4 are used..what is required to add another input.
is it just a straight feed from back panel to front selector via a 10kΩ resistor or am I missing something?
replacement transformer part numbers etc.
replace 3A with 6A rectifier...(maybe different edition..mine seems to have 1N54?? diodes)
Colin...maybe a list of serial numbers referenced to Issue number
