Title: Revox B77 mkII advice needed
Post by: Scar972 on September 26, 2015, 07:48:03 AM
Hi all, I'm new to the forum and need advice on turning my Revox B77 mkII to play Tape Project tapes.
My deck is the standard 3.75/7.5 ips version so I know I will have to mod it to play 15 ips tapes, I was thinking of adding the Bottlehead Eros Tape Head preamp to give me the option of switching to IEC eq., but what must be done to the Revox in order to use the Eros Tape Head preamp? Thanks in advanced!

You will need to rewire the playback head to a pair of jacks. Then those jacks can be cabled to the Eros. I have not done this conversion on a Revox so I can't help with the details, but basically there should be wires that connect the playback head to the internal repro amp and those would be rerouted to the jacks.

IIRC, the B77 is a 1/4 track machine unless special ordered with 1/2 track heads.
If that's the case, you will also need a different playback(repro) head.

If you're not familiar with the different track configurations on the heads, there is info included in the "Beginners Guide" located in a sticky above the General Forum (toward the end of that thread).

My Revox is a 2 track machine, I also have a Otari MX5050 B2HD, will need to decide which machine to go with if I have it modded for use with the Eros.
