[QUOTE="Reg, post: 94833, member: 3659"] There are several pots inside the surface mount PRO or the TDI and none of them adjust the delay. Please don't try to adjust any of the internal pots on the TDI or the Pro. Most are very critical adjustments. Some set the 0V out of the associated opamp and if out of adjustment, can cause serious grief. These particular settings are adjusted for less than 1 mv out with no signal in. The initial 200 TDI's made were through the hole pcb's and were basically like the GS 5 which used 4538's to set the timing. These units had an internal pot to set the minimum delay. If someone screwed with the internal pots, I would simply remove those that set the 0V. They are not needed, but there are several pots that still would be left, so without knowing what pots could be removed I strongly recommend none of the pots be tampered with. Reg [/QUOTE]
