PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please sub

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

Is the PL450 or the PL450B better? Whats the difference between the two? Reason I ask is because I mutilated mine last night trying to put it in a host. I ripped the pins out :(
 





Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

The 450B is better, however I bought one from techhood back when it was $50 for a "450" I sent him an offer of $40 and he accepted. However, I sent him an email afterwards saying I thought I was purchasing a 450b, not a 450, so if he can send the B version, or cancel my order if possible. He told me the non-B version is no longer manufactured, and so all they send out is the B version.

Essentially, the B version is rated for slightly higher power output, according to manufacturer specs. I don't know physically what has changed between the versions, different contact area, more/less gold wire connections, etc.

So what kind of current can we be looking at now for these B diodes?

This looks interesting. $45 for a Melles Griot HeNe Laser 10 mW with power supply, RED Beam. Im not bidding! :beer:


Edit: I was also looking for the PL450B online and noticed the price had dropped to under $40 in many places inc ebay and they all include free shipping, so that would be especially interesting for non US buyers.

No. HeNe lasers rarely go over about 20mw. I think there was one that could do 100mw and the tube was something like 1.5 meters long. Argon lasers can reach 10+ W and C02 can reach 100s if not 1Kw or more.
 
Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

OMG a 10W argon would be the COOLEST THING EVER!
 
Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

Eh, they go quite a bit higher than 10W. 20W is still fairly easy to find. A couple hundred is the record I think. The Grand Coulee Dam has 60W worth of argon (2x30W) for their light shows.
 
Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

Yeah but how much would you be spending on a 10W Argonator?

It really depends on model, location, condition, accessories etc. Usually somewhere between $1000 and $5000. The difficulty for most people is setting up three phase (sometimes 480V) and water cooling lines.

For grins and giggles I tried bidding on that yellow hene and chuckled at the ensuing bidding war. It sold for a little less than what I paid but I don't mind since it helped an LPFer in need.

I saw a couple in the 10+ watt range on flebay last night. Most of them cost $1500+ (more with PSU) and require 3 phase 208/220/440 power which is next to impossible to find in residential areas. There's an ArKr there that I'd practically mortgage a kidney to get.
