Vintage Synth Repair

hey, first off a disclaimer, I'm sorry if this list is strictly for 
the discussion of repair, I just assumed that the majority of those 
on this list would have quite a detailed knowledge and a lot of 
insight into what I am curious about, if this is inappropriate for 
this list I will gladly exit stage left =-) thanks for your 
cooperation and on with the show!
hey all, I'm new to the list and I guess I'll start with a brief 
introduction. My name is Kevin and I'm from Seattle/Olympia wa and am 
currently enrolled at the Evergreen State College. I have a deep 
interest in vintage musical equipment as I play guitar and have for 
quite a few years (I'm 21). The reason I chose to join this list in 
addition to the fact that I'm very interested in reading the postings 
is that recently I purchased a Roland Space Echo-150 after saving for 
quite a while and have been using it about non stop for the month 
I've had it. I have been interested in tape echos for quite a long 
time and am very interested in the history of the machines, as well 
as personal stories and interests in them of others. I am now doing 
research for a paper on tape echos and the pulling of them off the 
production line in favor of digital, a comparison/contrast paper i 
suppose, although I am concentrating more on the analog tape echo 
side of things...I am particularily interested in why they were 
developed, ie. what brought on the craze in the early 70's, I am 
aware of course of the psych scenes deep interes in the Binson's 
Echorec and the echoplex and that the space echo particulary came 
about as competition to them. Also the implications these machines 
had on the recording world and what exactly they changed and paved 
the way for. I am also aware that the the RE-100 was first brought 
into production as a tape delay unit designed for the reliable 
playback of long announcements (altho I don't quite understand how 
this worked with a shorter tape delay) and perhaps these announcement 
machines were adopted by guitarists on a whim. Ok, well sorry for the 
novel of a first post, but I am very interested in what all of you 
have to say and look forward to hearing your responses, feel free to 
email me off list if you feel the need as I didn't quite understand 
the reference made to "once there is enough emails a digest will be 
sent out" Alright, thanks for your time and patience

In case you didn't know, there is an ' Echoplex ' list. It does not seem
that there are many posts, but everyonce in a while!Vintage Guitar had a
series of articals a year or so age about tape echos. They said first was
the Echophonic made in Midwest for a guy named Del ______(?).

 PS: I used to mess with a Yamaha SK-20 polysynth thru an Echoplex. It
was a fun thing.
