schematics question (with attachment)

[Sho_Bud]

I'm trying to fix my roland space echo. The reverb stopped working. I'm trying to poke around with my multimeter set on continuity, but i've just recently started trying to learn electronics and i'm limited with reading schematics.

In the space echo schematics that i've attached, i first can't figure out which end of the reverb unit (outlined in RED) is IN and which is OUT. I've connected one of the multimeter probes to the IN (or OUT... again, not sure which is which) RCA cable of the reverb. Using the schematics i can see there is a connection at point #33, so i'm following the path and i'm not getting continuity after the component that i outlined in blue. Not sure if there should even be continuity.

Can someone point me in the right direction?

i color coded the connection points on the reverb. Hopefully someone can tell me which is which. hopefully i've supplied enough info.

Thanks!

Welcome Sho Bud,

I know nothing about this circuit but I can see that the green port is an output from the op-amp and the yellow port feeds into the base of Q10.

Between E and 32 you should see a signal. A scope would be best but a meter should be able to pick it up also.

Hi Alan, Thanks for your reply!

Not sure what you mean by "Between E and 32 you should see a signal"?

Could I connect points in the chain directly to an amp with a speaker to see if i get signal out the speaker?

I have an old Tektronix scope that was my grandfathers...it hadn't been turned on in a long time until just the other day. Do you think i would need to get it calibrated? I also need to buy some probes.
