Co2 LASER BLOW OUT!!!!!

Weak or DOA tubes 5 Tubes for $100 in the usa!, $145 delivered anywhere in the world!

Lasing tubes with RF amplifier driver board attached and running OK @ 5 to 7W output! ONLY $150.00 delivered in the USA or $175.00 ABROAD to anywhere in the world!

Also, i have a limited amount of RF MOSFET transistors left these are $25.00 delivered anywhere in the world. You will need a 3 to 7W RF signal to drive it, an old CB radio will do fine. These have a VDS rating of 450V and a switching speed of 120MHz and a power output at 120mhz of 80W, tyhey can put out A LOT more power at lower frequencies, they do 150W at 27MHz without even getting very warm...


OMG!!!!!!!!! THAT"S ONLY $150 to $175 FOR A WORKING RF CO2 LASER DELIVERED!


Hopefully there will be interest in these!

;D Current orders! ;D

how much would shipping be to canada Postal code :p0h 1k0 for the cheapest insured.

Re: GB FEELER Small RF 5-10W CO2 LASERS! CHEAP!
 
I would be interested in one

Gimp :)

Chris --

I'm in for one working system. *

I hope this offer isn't flooded by posts like - "I want one but don't have the money" or I want one but won't have the money for 2 years" etc etc.

Let's have a buy here without wishers posting. *I commit to one unit. Here's a chance to learn CO2, RF electronics and have fun.

Mike

Re: GB FEELER Small RF 5-10W CO2 LASERS! CHEAP!
 
I am definitely interested in two complete working systems also. These look very nice!

Re: GB FEELER Small RF 5-10W CO2 LASERS! CHEAP!
 
How much for a complete system (power supply, tube and all)?
I may be in for 1...

disma 11-01-2008 09:31 PM

Re: GB FEELER Small RF 5-10W CO2 LASERS! CHEAP!
 
Heres a funny thought... Do you need to check the SWR of the laser tube? ;D

heruursciences 11-01-2008 11:23 PM

Re: GB FEELER Small RF 5-10W CO2 LASERS! CHEAP!
 
I'll tune them for you. You will not need to check the SWR since i'll be doing it for you :D

Re: GB FEELER Small RF 5-10W CO2 LASERS! CHEAP!
 
:D I hope there is a lot of interest in these, they really look like an unbeatable deal! :o I dont mind building a hs, Lets make 1 a fully functional system and the other one needing the heatsink, how large does the hs need to be? :-?

heruursciences 11-01-2008 11:57 PM

Re: GB FEELER Small RF 5-10W CO2 LASERS! CHEAP!
 
Trust me if you have no experience tuning RF stuff you don't want to go there! That's why i'll be doing the tweaking and tuning, but when you attach the heatsink to the small preamp board for the cheaper ones, you'll need to re-tune it a little. A pentium cooler will work fine for the preamp transistor, the power fet i'll bolt that puppy right on the tube frame for ya.

Those RF fets for raw tubes are like $70 each *surplus* and pop quite easily if you go way out on tuning. Fortunately i got a crapload of them, and bought quite bit cheaper than normal though. ;D

So in for 2 plug and play units then?

Spyderz20x6 11-02-2008 12:00 AM

Re: GB FEELER Small RF 5-10W CO2 LASERS! CHEAP!
 
NVM, i don't want one...

disma 11-02-2008 12:08 AM

Re: GB FEELER Small RF 5-10W CO2 LASERS! CHEAP!
 
ok, I am still in for one p&p, and one needing the hs, if its the preamp thats needing to be tuned, it wont fry the big output transistor will it? Cant you tune it with a scope? :-? and will the laser need to be tuned after it has ran for a while? Nice that there isnt any HV on these. not really any danger of getting shocked. (unless you count the rf as hazardous) :) I used to p&t cb's 20 years ago. ::)

Re: GB FEELER Small RF 5-10W CO2 LASERS! CHEAP!
 
The ARF- 449B are unbelievably tough SOB's, they can take 100% SWR at under 160V p-p. What they can't take is mismatch of phase that in effect creates a constant +Ve on the gate that keeps it half on all the time. You can tune it with a Rf amp meter, null meter, VTVM, scope or a combination of the above; volt meters must have the shortest lead length to the resistor to measure without causing too much parasitic C. Remember parallel tank circuits want the highest voltage but lowest current draw under load, and series RC circuits you want the most current flow through with the highest voltage across the C. The tube is in effect a LC antenna circuit.

I have a BIRD power neter and a 100 MHz 'scope.

Mike

Re: GB FEELER Small RF 5-10W CO2 LASERS! CHEAP!
 
It looks like there isn't much interest for a 20 piece GB :(

Chris -- I'll give it a couple mor days and then I'll contact you for final specs and price.

Mike
