after spending the best part of the week changing all the micamolds/paper
caps in this particular ar88 i find i now need a big (tuning) knob to
complete the job anybody have one they could spare?
the radio by the way now works with good sensitivity down to 30mhz!!
now to tackle the ar88lf and the grey (navy?)ar88d


**** AR88 is identical to AR88D (with some small variations-see below),the
88 was intended for rack mounting,the D stands for "Desk" and indicates the
addition of a cabinet.If the receiver is marked 88D then it originally came
with the desk cabinet from which it has become seperated.
If what you refer to as an 88D is originally grey in colour,it will most
likely not be an AR88D.You would have to ID all the control knobs,their
layout and their nomenaclature .There were some variants of AR88 which had
an additional front panel control,these were part of DR89 Diversity
Communications Receiver
There are several variations of the 88 family,some are :-
AR88,AR88D,AR88F,AR88LF,CR88,CR88A,CR88B,CR91,CR91 A and so on without
mentioning some of the military equivalents (or sub variants of their own
type!!) The CR prefix refers to "Component Radio" as in "CR88A is a sub
component of DR89A Diversity Communications Receiver".
Let me know the front panel layout and frequency coverage,I'll look it up if
I can (a picture on alt.binaries.radio will let everyone have a
look).And,sorry,I can't help you with the knob.
