My reference to Takatsuki was to do with the price previously being $4,299 for a pair of TA-300B which is now available from Bryan at Finn Bespoke currently for $2650 which is a much more reasonable price. https://www.audionote.com.au/takatsuki 3 Link to comment Share on other sites More sharing options...

This is now intriguing. Might a mini review be forthcoming soon? Or just a few hints on what is going on under a very well crafted bonnet?

The A2900 are being used in a specific driver role here for the push-pull 6550 configuration in the TVA-1 with 300+ volt plate voltages experienced across these valves. Hence why a beefed up 9-pin mini is needed here. It sounds the best it's ever been for decades! Who would have thought the A2900 is the only solution for this amp without a circuit design modification. 1 Link to comment Share on other sites More sharing options...

Willmax Posted July 1, 2020 Share Posted July 1, 2020 After a long wait, partially due to Covid-19, I've been fortune to be given the opportunity to pick up this classic valve amp. Thanks to a good mate of mine, I'm totally stoked So without further ado let's see if you guys can identify which amp this is, it should be an easy one I'd imagine. 4 Link to comment Share on other sites More sharing options...

Now those valves you posted look funky, are they NOS or new production? I'd be keen to hear any tips on valve options I should consider as most of the ones installed came with the amp, apart from that single KT120 which is a new one replacing a 6550 originally. It made a big difference to the overall sound for the better IMO. More dynamic, punchy with greater but tighter bass slam if that makes sense.

xlr8or Posted July 1, 2020 Share Posted July 1, 2020 (edited) Those 6550’s are Tung Sol solid black plate 1950’s and cost a bomb - to be more specific they are version 2 of the black plates. There are 3 versions of the black plates that came out in the mid to late 1950’s. The first version had a top D getter only, the second version had a top D getter and double D getters on one side (the ones shown) and the third version had a top O getter and two O getters with one on each side. @WillmaxTry looking up how hard the D115 runs the 6550’s before determining whether to get NOS/UOS or new production valves of the 6550 or KT88/KT120/KT150 types. There is plenty of info out there and a good starting place is the link below, which will also confirm the Mk version you have. https://www.arcdb.ws/ Edited July 1, 2020 by xlr8or Link to comment Share on other sites More sharing options...
