![]() ![]() What do you think about their function?Ģ. Is the schematic an improvement on the implementations, or vice-versa?ĭoes in tot matter which way round as long as there's one connecting to each of the grounds?ĭo the values of R101 and R13/14 depend on which ground is being used? What are the consequences of each way of doing this? The schematic shows R14 between the collector of TR1a and DUMPER ground, whereas the implementations connect TR1a collector to SIGNAL ground through R13Ĭonversely, the schematic shows R101 between SIGNAL ground and Q45(TR11) collector, whereas the implemetations have R101 connecting to DUMPER ground. I was looking at an early revision of DCD Mod4 and see that Keith in a later revision changed R101 to go to DUMPER ground. This is in line with the illustrated implementation. ![]() ![]() R14 is still replaced by R13 in the implementation, which does still go to signal ground. This raises the general question of the ideal schema for internal grounding in amplifiers. ![]()
