Not really mistakes ... does the amp not work or something?? :?
He obviously just found some other way of doing it and liked that enough at the time to make it the way it should be in production... till he came across the next one of course...
and if any recto revision is to be considered a mistake, then a lot of other companies will burn in deepest hell for the sins that are their entire product range :lol:
The mistakes are forgetting to draw a circuit path and having to connect it point to point. No one said they could not make it work, but it is a mistake regardless. We are not bashing any revision, but we are pointing out the obvious.
If you want mistakes that cause malfunctions, just look at the first four revisions and three service bulletins for the RK 1. Arcing traces, channels dropping out until a full transistor upgrade and bad pentode/triode switches.
Owning one was such an inconvenience, someone should burn in hell for that.
