Whites Classic I Mod in process

[JJdigs]

Tonight I started beefing up a classic I ....My first step was to replace the two resistors on the board. I read somewhere that replacing the two resistors really help with depth. They came out pretty easy for the most part. I just had one stubborn hole where I could not get all the solder out to slip in the resistor. However after alittle bit of heating it up more with my desolder sucker I got the rest of the solder out. After putting it all back together I was amazing at the extra depth. Stock it would air test a quarter at 7". And now almost 10".... Very cool ....

Next iam going to add the GB pot, then a led battery volt meter which will be activated by a push button, which is small 1"x1". Then if I can wire it properly, I will add dual disc knobs, kinda like the Tejon or 1266x. And if all that goes swell....Iam going to add a audio led signal meter...That show signal strength , kinda like a anolog meter but it has led lights ! Which will be activated by another ouch button above the toggle for dual disc. More to come soon !

fun hey isn't it good these older machines can be fiddled with and made better, good luck and sounds like your having fun

Yes AmberJack it is alot of fun. I have always played with electronics but never dared to mess with a detector....Until I found a good deal on a classic to hack up !

thanks JJdigs for the photos just to confirm the depth mod is replacing the capacitors with the values on the blue paper in to the slots I have put the white arrows on?

just want to clarify as I might have a go if I find one for cheap of someone else does.. any other photos of the upcoming mods would be great too

thanks hey it looks like a fun project keep us updated

again well done for taking the time to share!!

HI JJdigs.

Nice project.
What about building in the white's coil connector?
That way you can use easily all 6 kHz range coils made for white's.

[JJdigs]

Yes that is 100% correct.

 

[JJdigs]

I plan on doing that...I just got a whites 5900 series three in where I can compare coil connectors so I can order the proper parts....I really wish I could use the blue max series coil instead of the 6b style coils. But oh well !

Looks like a great project! I'm still in the tube days- and lost.

 

[amberjack]

Yes that is 100% correct.

Thanks

I just wish I knew if VR2 was the sensitivity potentiometer. Does anyone out know for sure. Thanks

 

[amberjack]

I don't know, but from what I can see from the wide shot there is a few on the board what would they be for Sens, GB, Disc, maybe test the resistance but still without specs its a guess?

sure someone will know

JJ,will this mod work on a IDX Pro ?? as i have a mint condition one which i have final plucked up the courage to do a few mods too,change these resistors over and also the manual GB mod as well.This will do for starters and if it works out OK i may do the other mods that most folks do.

Nice project JJ!
I've tinkered with my Tesoro compadres a bit.
Waterproofed one and added extra disc circuits to the other.
Going to stay on the lookout for one of these older whites units to try out!
Thanks for posting.
