Dual Rectifier Tremoverb question

[webstersp]

I just bought from ebay a Dual Rectfier Tremoverb head and I am looking for a good
effect rack to go with it. I wanted to go with the G-Major from TC-Electronics but I have read
that it sucks in parallel effect loop....

I want to add an effect rack to my gear and I hate using pedals...
Is there another rack that could work great in Parallel or should I sell the head
and find something with serial effect loop? (hope not!!)

you can mod to serial by replacing 1 wire

I have read somewhere that with the schema an amp tech could do this epretty easily.
Someone can tell me where I can find this parallel to serail tremoverb schema?
