Just joined after a long time of reading threads on here. Always been a tinkerer, though my desire far outweighs my technical knowledge. I know enough to not shock myself or potentially blow something up, but have yet to actually build anything. I do know how to solder, can build many things well, just never really ventured into electronics.

I do love my Class A stuff and am looking into a JLH 1969 amp as my first project, likely in the form of a kit, then build a power supply for it.

Anyway, I will be reading and searching quite a bit, more than posting.

I hear there are some knowledgeable folk in Central America.

The JLH is not only good to work on, but sounds good too. You may need to stabilise it using modern transistors. Do you have an oscilloscope?

I do not have a scope. I know that will limit me in my tuning, but was hoping to follow a few of the recommended upgrades to current and better transistors etc, from a few proven builds, just to get a functional amp to start with.
 
..and you should. Keep in mind that amplifier stability and oscillation is not a matter of tuning, but troubleshooting. It can depend on your layout even if you follow instructions and it can be difficult to detect even when it's happening.

As of yet, I wouldn't know what to look for buying an oscilloscope, nor best practice on using it. But, it is something I do intend on getting the knowledge to use and become proficient with.
