[ATTACH=full]22077[/ATTACH] Hi ! Thank U for ur recent purchase on the Maco 750 kit. It will be in the mail manana.
Finally found 1 of the 3 Maco 200.
Whoo. The last time used one was over 39 years ago LOL ! Did not find my first one.
It's
buried deeper in the garage in a box wrapped in plastic. This one. Picked it up a few
years ago at a garage sale/estate sale. $25.00. At least. two strong 80%8950's ! Am a
sucker for vintage tube gear at garage sales.
A lot of time has passed. Guess not a Newbi Golden Screwdriver anymore.
This box is CRUDE. Poor layout of tubes. Compared to the Palomar Skipper 300.
This is a poorly designed & implemented product electrically.
It is interesting how much it looks like yours !
After finishing the D&A 12 tuber promotion to Warrior. I will tackle these Maco 200's
This one had 1 6KD6 driving 3 8950. Neat "gimmick" with a diode to put approx 6.3
heater voltage unto the 6KD6 fillaments. The remodel of this unit will be.
1) Cutting out a new hole. Repositioning the driver.
2) Proper final tank coil. Possibly driver tank. Removal of the button variable capacitor.
3) 5-40pf small air dialectric variable capacitor. Like the Palomar Skipper.
Have several working Skippers. All I have to do is measure the Inductance of the tanks
on the Skipper. & roll my own. I will experiment by using 1/16 copper tubing that will be
plated with pure silver plumbing solder. Most likey the Iron in the Maco is not as Stout
as the Skipper. Skipper uses a separate heater/fillament tranny.
Parrasitic supressors on all anodes. & hose clamps. The clips on the tubes are just
garden variety hose clamps.
