I have two of these transceivers, both EBay purchases.
The first was a well-used example but fully serviceable, and fully loaded with narrow SSB and CW filters.
The second one was described as being in pristine condition, but with an output fault, and the price reflected it's non-fully-working condition A bonus with this unit was that the previous owner had tried replacing the output tubes to cure the problem. It's also fully loaded with narrow SSB and CW filters.
The TS-530 is legendary as a superb piece of equipment,
Both transceivers drift quite a bit, I intend to try to improve the situation, but it's not very high on my list of my priorities.
More details and pictures to follow, but full output has been restored after an interesting bit of fault-finding!
