If you want a radio to modify; then the 980 isn't that radio. It will fry. Use it as is - or not at all. Or find out the hard way with your own cash. But as it is, it does very well w/o modding.
To get a radio re-capped should go for about $60-$75. Alignment is about ~$50/ish, depends on if it is a AM only or SSB radio. AM only radio alignment should be about ~$40; recap about ~$45.
If you want a SSB radio; then do not mod it for AM performance, as you will have crummy SSB performance. The only mod that works well with a SSB radio is getting it peaked, as this also improves AM performance w/o ruining SSB performance without the need of stupid hacks/mods.
There are a couple of guys I would not send a radio to, such as Snake Radio. As he just charges too much money and will chisel all he can - or he won't want to do the job.
Just my experience . . .
