Your technique is absolutely beyond reproach and is the same as I was taught - "heat the part not the solder" as well as not reworking joints solely for the purpose of improving aesthetics. I absolutely wasn't suggesting you didn't have the right technique, I was only trying to highlight some cautionary points for the less inexperienced hobbyists who will be following your phono stage project with interest (as have I). The preferred temperature obviously depends on the solder composition and choice of flux - FWIW I also use 700F for my 60/40 leaded solder (for home jobs I still use leaded solder). However, high silver content solder is often promoted for use with audio and this requires a bit more care in adjusting the time of contact before applying solder. Anyone unused to the challenges of high silver content solder will generally wind up the temperature to achieve the same heating time for solder flow that they are used to. The main issue is around the long term reliability of joints and the higher temperatures used in this manner will be a greater risk for weld integrity.
Your project has certainly piqued my interest to experimenting with a tube stage! Thanks for sharing it :)
