How to post on Wanted section

I just bought a Marsh 400s amp and looking for a Marsh preamp. How do I post one wanted section?

Also anyone has some feedback of using other (good used budget) preamp with Marsh SS amp? I amĀ 
planning to temporarily use Marantz AV 7008 as a processor until I find the Marsh p2000b.


Place a "For Sale" ad and state in the heading "Want to Buy Marsh Preamp"and set the price at whatever you are willing to pay for one. Nice amp btw.

Yes, you start a "For Sale" ad and enter information like you are selling one, but under "Category" select "Wanted".

Thanks all for your information.

Maybe ask Audiogon.
