Is the hand wired TT still available?

Only second hand. I had my hands on one last year. Wish I've bought it...

Here's an an ample of a hand wired amp with turret board construction.

excellent post sir

In fact apart from the rare modern Custom Shop amps Oranges have ALWAYS been PCB construction. Though they used to chassis mount the valves instead of mounting them on the PCB itself as is done these days. However if the board itself is strong enough (yes) and is properly reinforced with spacers (yes) than unless there are any heat related problems (not so far) there shouldn't be any real big reliability issues. :D

Properly done PCB is just as reliable as any other build method, and is actually less likely to have noise issues due to random positioning of wiring, components etc. With PCB build everything is all laid out pretty much exactly the same from amp to amp. It is really just cheaply put together PCB electronics that give the technology a bad name. But a poorly built amp is poorly built even if that is all done PTP by hand! :wink:

PTP is in no way inherently more reliable than PCB. See this thread HERE comparing old Marshalls and Hiwatts, in particular posts #15 and #22.
During the later 70s Marshall went to PCB construction, but the reliability didn't drop at all at with that change. It was only years later (around 1990) when that happened, when they introduced a new range (JCM900) which were built to a price instead of to their own traditional high standards. The 70s Marshall amps (both pre PCB and PCB built) being discussed on that thread, alongside '70s Hiwatts, vintage Oranges and just a few others were (and if well maintained still are!) about as reliable as any amps ever built.

Remember though, there is more in many modern amps to go wrong than with those simpler older amps. Have a look at the inside of my OR120. Ignoring the (non original) doubled up capacitors on the PCB there is a lot less happening inside there than in your RV, right?

Your amp (like my Rocker 30) is put together to a pretty decent standard. Not the worlds best quality, but no huge issues either IMO. (Use of press on spade connectors being by far my biggest complaint!) Well above average run of the mill build quality at any rate.
But... with more complicated circuitry like the more complex modern amps there will inevitably be more potential for things to go wrong. Thats just the way it is and the reason why a lot of us believe simplest is usually best. Even so the vast majority of all problems with good quality modern valve amps are with the valves themselves. Keep a couple of spare valves and fuses handy and you and your amp will be fine!

Happy? :)

We now can add the total hand-wired Shiny Terror/ 10th Anniversary Tiny Terror to the list, which distinguishes itself from the previous hand-wired TT by being hand-wired without a turret board.

But I thought the original hard-wired TT didn't use a turret board either?

Indeed! :lol:

With the new one you are paying for 'shiny' - shiny costs! :wink:
