RedHeat

Have had a "go" on 4 chips---in photo,looks to be scape marks after the LM & LF's
would this have been were the number was? is there enough info? If so I'll do the rest.

Nakky--have filled in those parts you marked:

Think yes. Also would be great know other last three.
The big one should be 4024.

Will have another go at it tomm- morning. And will label everything thats not clearly
visible (about 25 comps).

REDHEAT

This looks to be about the lot. 1 comp- with no visible markings.But I'm sure you
will figure it out.

It 's another version of the Eldorado schematic.
Could you clarify :
R13 = Brown, Red, Broown = 120 ohms
P1 = ?
P2 = ?
R23 = is it</SPAN>connected toP1 ?

</SPAN>

P1 & P2? Controls? Left is Disc, Right is Boost.
All other controls/parts etc are in the
battery box under the arm cup (No photos of this are possible)

R13 & R23 see other photos

Not about to take it apart again,having already spent lots of time cleaning,supplying component info etc.
Did I waste my time guys???

I seem to remember talk about Vic's metal detectors way back in the mid 1970s.
Some 5 to 10 years before the Tesoro's came around
I may be wrong here, but maybe the 'Eldorado' from Tesoro is a version of Vic's 'Red Heat' machine and not the other way around.
It is certainly possible and just a thought.

My RedHeat was made June 10th 1993
(see my dated/signed machine photo earlier)

The Eldorado was introduced about 1986.

Hi all, i have just purchased an old minelab tribune in VGC but it is not working there seems to be a wire on your picures that is not present on the pcb of mine? i bridged this but it still did not work.Sorry im a complete novice with fixing detectors so was wondering if anyone was quite knowledgeable with this model?
Many thanks!

Thanks!

[superchuckles]

since nobody seems to have a schematic or service manual for the compass magnum 320, could anyone tell me the values for R1000, R1003, C1000, & C1001. thanks.
