How to add the effect loop to Marshall 1987

[rotation]

Hi!

I just repaired Marshall 1987 amp. Bias was way to high, two capacitors were leaking, voltage selector was not conducting well...
Owner asked me to add the effect loop to, but i really dont know where to put it. Can anyone help me? Please?

Hi. I just post a thread about add an effects loop to my 2203. A friend of mine asked me to do the same to his 1987 Plexi.

Superleadfixer, do you still have this diagram? Please I need help in this one.

Thanks in advance.

Is this a buffered or un-buffered loop? I've been wanting to put an un-buffered loop in my 2203 for a while, but worry about the change in tone. I need it so I can throw an EQ in the loop for solo boosts... you all know how it is with a single channel amp.
