content: At the time of posting, there's 3 Metcal PS2E-01 soldering stations on shopgoodwill.com for $9 each (link below). Have one my self and totally recommend snagging one if you are looking for a solid station. You will also need to snag a MX-500 hand piece and some compatible tips. I recommend the Thermaltronics ones. You can find a pretty reasonable price/assortment on Amazon. Just make sure they say compatible with the MX-500.https://www.shopgoodwill.com/Listings?st=metcal&sg=&c=&s=&lp=0&hp=999999&sbn=False&spo=false&snpo=true&socs=False&sd=False&sca=False&caed=5/9/2018%2012:00:00%20AM&cadb=7&scs=False&sis=False&col=0&p=1&ps=40&desc=False&ss=0&UseBuyerPrefs=trueEDIT: Disclosure, I am in no way affiliated with Goodwill. Just found them randomly and figured I would share for those looking for something similar.

content: There is an issue with your link. This link worked for me.https://www.shopgoodwill.com/Listings?st=metcal&sg=&c=&s=&lp=0&hp=999999&sbn=false&spo=false&snpo=false&socs=false&sd=false&sca=false&caed=5/9/2018&cadb=7&scs=false&sis=false&col=0&p=1&ps=40&desc=false&ss=0&UseBuyerPrefs=trueEDIT-no it doesn't either. Just type in shopgoodwill.com and search for Metcal.

content: Information on METCAL PS2E-01 Soldering Station:See attached Control Board layout, then read through the testing below.Testing: 12/27/20Status: Probe connected, Green LED ON, Stable at Temperature (melts solder)Voltage with respect to Ground (EMI Filter tab):TP1 9.4Vpp @ 16Vdc Q1_c outputTP6 112Vpp @ 0Vdc Feedback pointTP7 17.2Vpp @ 3.6Vdc 13.5MHz oscillator driveQ3-d 40Vpp @ 15.6Vdc OscillatorQ4-d 76Vpp @ 20Vdc 13.5MHz Power DriveU4-7 42Vpp @ 19VDC PWM Regulator output (D3-K)J1-center 66Vpp @ 0VDC Probe 13.5MHz SourceUsing TDS360 scope triggering normally on Q3-d, grounded on EMI filter case, and verifying DC values with Fluke 115 DVM.Temperature readings with Infrared Thermometer about 6 inches away with Tamb=56ºF:Delta above TambQ1-c 126ºF 70ºFU4-top 95ºF 39ºFU1-top 135ºF 79ºFL5 145ºF 89ºF hottestRepair: (2nd PS2E-01 unit I’ve worked on with same failure mode)Found Q1 to be dead – Base-Emitter junction blown open. Q1 is a ZTX749 which has impressive ratings of 2A/40V, and an unimpressive minuscule size. Replaced with 2N2905A with TO39 package to which I added the red Heatsink shown in the attached Figure. Note that it runs quite hot at 70ºF above ambient.To solder on a new Q1 will require disassembly of the Main Heatsink which is somewhat tricky.Notice the location of the insulators when taking apart. Take pictures.U4 does NOT require an insulatorQ4 drain connection has to be made with the metal ring on the center screw. Getting the Gate and Emitter pins inserted takes somepractice.Q3 does require to be insulated.Recommend leaving everything loose until all nuts/insulators are in place – then tighten. Then verify continuity or lack thereof.Minimize the flexing of the Switch/LED assembly or the wires will be fatigued and break off.The Schematic is unavailable. Use the METCAL MX500 Schematic. Only differences I've noted are:U4 is L4960Q4 is IRF130No U8 that I could findSingle Probe so J2 and S2 are not used.Also note that TP1 is between L1 and L2, TP6 is between C30 and C29, and TP7 is at the gate of Q3.Have fun repairing,George

content: I am very grateful to you for your material. !!!I have this station not working. There is a burnt resistor R16, near Q1 an inductor L10 and a capacitor C20. it consists of 2 capacitors of 50 pF connected in series. are you able to give the correct denominations?I will grateful to you
