Why would you have corrosion in this area unless there has been moisture or in an airborne contaminated area? Craig No CORROSION, but certainly OXIDIZATION. Wherever you have electricity flowing throu

I'll second Dave Wise's statements. My rules-of-thumb for replacing tantalums - in order of preference: 1. Film caps where they will fit - same or slightly higher capacitance, and generously higher vo

Are those Spectrol Potentiometers? Takes me back nearly 50 years, to when I was just starting out as a green technician!

Jeff Choosing a substitute resistor type, as others mentioned here, is not a simple matter. You really need to know what its function is in the circuit. Carbon Comp resistors are the only absolutely s

Dave, That this is the amount of ripple current the cap can take to make the lifetime spec? YES A spec with twice the ripple for a given lifetime can take more power supply noise? YES A UCY2C470MPD1TD

Mark Vincent is spot on regarding electrolytics. Film caps - Polyester (cheaper and smaller), or Polypropylene (larger and expensive) are usually a no-brainer ultra-long-life substitute for tantalums,

Jean=Paul I have a fully-overhauled PSU available in stock Check CondorAudio website homepage, and my email is in RED, in the middle of the page. M Yachad

With this problem, I always use my Variac to generate sufficient AC voltage to the input of any DUT, noting the minimum VAC it takes to activate the DUT. Absolutely ZERO guesswork, when using this met

"Panasonic also makes a suitable capacitor in that value. Nichicon doesn't (didn't?)." That's a sweeping generalization, and not quite 100% on the mark.. In fact, Nichicon makes perfectly suitable cap

Tom, I'm not a chemical engineer, nor do I claim to have any knowledge of how this stuff works. My technical knowledge is restricted to Electronics and Airplanes. All I know is that since the 1960's w

"Brasso IS quite abrasive, has Kaolin and crystalline silica in it." Thank you. Brasso is multi-use, and application methods are quite different when cleaning Tek contacts, as opposed to cleaning the

Cleaning those switches (and all types of copper or other contacts), is done perfectly with Brasso. NEVER use any abrasive material on any contact surfaces on any equipment.

Regarding the issue of causing damage to the SMD pads, using this method. Just goes to prove that there is no shortage of amateurs who call themselves "techs". I have repaired / overhauled HUNDREDS of

Steve I make up a custom kit for your exact scope. There are NO universal kits. The kit includes all the necessary components for the A1 A2 A3 A5 A9, and if installed A4 and A14. You can buy via ebay,
