[Central-Electronics] P&H DI-1 monitor scope?

[eugene at hertzmail.com]

Hi all, (if you already got this message, my apologies! I didn't see it
come through)

Picked up a P&H DI-1 Distortion Indicator on epay recently. Item looks
nearly mint. Inside looks bright and shiny like the day it (must have)
left the factory. Pix can be seen on ebay item# 220119145719

Is anyone familiar with this company/model? Looks very similar (but not
identical) to the central electronics MM series monitor scopes.

Of course, while it may look good, it don't work so good! 

It does not have the "TT-1" optional module that produces a single or
dual tone output.  
So now here is a long shot question.  So? Anyone have a "spare" TT-1
they would like to part with?

Thanks
Eugene, W2hx
Monitor scopes seem to follow me home these days! I have an SB-610
(needs work) a CE MM-2 (needs work) and now this P&H DI-1. Now, if I
only knew how to fix anything!
