    "No mess" is pushing it, some solid residue is left after removing the heat sink compound. I usually just blow it off w/ a bit of oxygen though. I swear by the stuff- a $22 12oz tub usually lasts...

    I disagree- a good flare joint should be no more likely to leak than a good braze joint, even though a crappy braze joint is far less likely to leak than a crappy flare joint.

    Can we agree that:

    Regardless of make, power surges shouldn't blow a capacitor- they are rated at at least 370V right? 5-6 years sounds about at the end of a crappy capacitors lifespan- keep up on the PMs as suggested.

    I've gotten in the habit of checking valves w/ the ELD before I remove caps or put gauges on. Also have seen a few 410 leaks only occur @ pressures >300PSI though this wouldn't apply in this case.

    I started using N2 while brazing about 8 years ago- not one new install since has had a TXV problem. The flowmeter is key- I use my Rx11 gun when schraders are not easier.
