Hi Ivconic,
this transistor or diode must have some number on it??
If the oscillator is working fine with a trnasistor,i wonder how it would do with a pair of diodes instead
Maybe if you take off the varnish you can see the reference.
Regards,
Fred.

Oh i did that already. Very thin varnish film was over, but no labels at all under???
Funny...all other components in that Colt was with labels...only that transistor and few diodes (smt) was not?

[ivconic]

Refering frequency...hmmmm!?
I had 18cm DD coil (TS 800) with my Colt. Frequency was indeed 7kHz.
Newer Musketeers like XS and Advantage usually come with larger coil. I never saw Advantage with TS 800 coil???
So...could this be a reason of all confuse?
Could coil dictate working frequency, in this case? I think it is possible...
But than again...what about band passes designed for one explicit frequency? Maybe in this particular design band passes are not designed to be dependant strictly on particular frequency

Max...yes, that smt could be ordinary transistor. But..they already put BC..'s in conventional package there. Why bugging with smt transitor than? Or vice versa; why bugging with BC..'s, why not put all 3 smt's ??
Garrett did that on GTI2500; all transistors at output are smt's..
Something is misty here...at least for me.

Hi,
I don't know... maybe the smt one is selected about e.g. some parameter and the like.

Why SMT ? Uhm... could be many reasons, but since operating frequency is so low maybe the best explaination is that device is available just in SMD package.

I mean... maybe it's something really simple... but cause they wanna keep e.g. some parameters close to a particular value they choose one kind that will give such consistency... but probably the choosen kind was smd only...for example the BC807 seems to me it's just manifactured in sot-23 package.

So, if you suppose they wanna BC807 there, for example... they must use smd parts.

Of course, this explaination is not proved to be right... just guesses.

Kind regards,
Max

...

I searched my collection of photos. Yes those are photos of my Colt.
If you look label on pcb, it says "...XS..". Yet it is Colt. Some controls are omitted from front panel and jumped. At XS those existing on front panel. But the rest on pcb is same as on other Musketeer models...

[ivconic]

And look Advantage pcb!? Same thing but much wider pcb...

Hi, i am 100% sure that this is a normal diode ( = 1n4148 )

[ivconic]

You are 100% wrong!

No...you are 1000% WRONG !
Or you are not able to distinguish between diode and transistor?

[ivconic]

BTW...i see all 3 pins are connected? How come? All 3 pins have routes? How come? Diode with 3 leads?
Dont know....i will leave this stupid argue. No use from it.
Do beleive what ever you want. Just do not confuse everybody else here with false claims...

[ivconic]

And here is reconstruction i made over .bmp in Sprint Layout....
So....shut up! It is PNP TRANSISTOR not diode!

I've done this some time ago.

Hi,
what's happening here ?

The diode again ????

It's a transistor, no dubts.

If use multimeter you can read conduction over the 2 junctions... like two diodes...

Though they appears like 2 junctions... this is the same in all BJT... 2 junctions present in them, that's all.

Using a "smart" analyzer you could trick it... if connect this way... it will say there's a silicon diode there! Probably this is the joke here.

Kind regards,
Max

[Fred]

To argue, arguments are needed.I see no aguments here, just one says "yes" and the other "no"
Maybe developing you respective ideas we could learn something

Fred.

I think this could be the source of all troubles...

The source or the answer??

Hi Fred,
disc is still average... I can reduce ferrite impact in all-metal... but in disc mode I get signals from nails... hammer etc... not when they are close to coil, but at distance.

What about your PCB ?

Kind regards,
Max
