 The indicator LED can be soldered directly to the PCB.  If you are using the TRXPN board, refer to that documentation on how to install the expansion board properly. If not, be sure you jumper XS and XR pads together on the lower right of the TR PCB. ...

 Leave enough clearance between the wires and IC6 - IC8 so they do not pick up any clock signal.  The indicator LED can be soldered directly to the PCB.  If you are using the TRXPN board, refer to that documentation on how to install the expansion board properly. If not, be sure you jumper XS and XR pads together on the lower right of the TR PCB. ...

to use either two MN3005 or four MN3008 (if you include the optional expansion board; the TRXPN). With the recent release of the Xvive MN3005 clones this project is suddenly much more viable for builders not lucky enough to get their hands on NOS MN3005 chips (which can go for as much as $40 a piece these days, if you are lucky to get ...

active and can be used to boost the bypass signal. Personally, I like this option as the circuit's higher voltage provides a nice clean boost at low LEVEL settings up to a mild overdrive at high settings. If you are a true-bypass purist, use the second wiring diagram. This completely removes the circuit from the bypass mode. Buil ...

you how to do it by ear. For scope biasing there are a few guides online the give lots of detail on how to do the procedure. Here is one guide you might find useful for scope calibration: http://www.davidmorrin.com/home/trouble/troubleeffects/electro-harmonix-memory-man/eh-7850/eh-7850-calibration Before biasing, let's unders ...

Here the biasing is done differently with the bias voltage applied to the non-inverted input of the op-amp. At the outputs, we have a new trimmer, BAL. This trimmer is used to align the two output waveforms for cleanest delay signal obtainable. After the BAL trimmer the signal gets sent to the second and final gain recovery stage. A ...

as the volume input on pin7 of IC6 (this balances the signal volumes between the two BBDs).  Disconnect the power supply from the circuit and install IC7. Reconnect the power supply.  Connect your audio probe to pin3 or 4 of IC7. Do the same type of adjustment to BIAS2 to get clean delay output.  Re-connect your audio probe to pin7 ...
