In fact I have a slight preference of it over the 300b ... ymmv as usual. I don't use KT150 tubes though. I will use KT88, KT77, EL34, 6550, 807, etc They all sound good, it is all subjective and depending on what type of muisc too 1 Link to comment Share on other sites More sharing options...
Odyssey Posted April 9, 2021 Share Posted April 9, 2021 Can you take a shot of it from above or the front. I want to see the whole amp to see how it looks. Yours is using 6as7 right? Link to comment Share on other sites More sharing options...

Next year will look at building the woofer box to complete the project. I used to have a few of Eric's amps but the 6AS7 is what left becasue this is the one that sings best with my setup. I am a good friend of him, I think I have tried most of his amps, and we had a few get together sessions to try out his different amps...etc. and actually I have his first 6AS7 amp, as you all know 6AS7 is very popular in the headphones amps world. So I asked Eric to design one for me using the 6AS7, it was started as a power amp to go with his 12AU7 pre amp. Since then my 6AS7 has gone through many rounds of surgery, upgraded to a stage that Eric said there is nothing to change.... it is now an integrated amp without any caps. It still has his marzE transformer which is now discontinued. I also added bits and pieces myself to change the look a little. Timber trim on the sides, big solid aluminium knobs and removed the words on the front panel also changed the feets to viprapod cones. I see it here now. It's gorgeous. Looks good with the interstage transformers even if it looks a bit crowded. I bet that will sound great with headphones too. I should show Eric this.... 1 Link to comment Share on other sites More sharing options...

The McChanson 300B )Shuguang Black Treasures) is to the right [next to the Elekit (then 5881) SEPentode amp]. I am trying the 6FD7 driving tubes with adaptors. In the front is the Line Magnetic EL84-based 219iA Mini SEP & headphone amp (3W output). Back left is the king--the Line Magnetic 518iA SET 845 amp. Feeding them in the very back is the Leben RS-28CX valve preamplifier (with phono). Other sources are the Clearaudio performance T/T (with Maestro Wood MM); the Naim NAT-01 tuner (hidden); the Audionote CD-2 CD player and the Cambridge CXN streamer. Speakers are the Tekton Design Perfect SET 15 (98dB + 8 ohm). 2 x REL Storm5 subs are stashed elsewhere out of frame. I rotate through the amps according to whim and specific music. The FM radio (ABC or 2MBS Fine Music) via the 845 amp takes some beating. It's a tough gig but someone's got to do it! Nice collection of tube amps. I have Elekit TU-8500 / TU-8200, Oblivion, a custom amp coming from Sweden using Sowter transformers and I'm thinking of getting Eric's 300b or his KT150 amp. 1 1 Link to comment Share on other sites More sharing options...

Odyssey Posted April 11, 2021 Share Posted April 11, 2021 Finally got to try using the KT88 amp driving my main Axis LS88. New respect for Eric's amp now. Sounded better than my vintage Kenwood KA 3300D. I'm so looking forward to the 300b amp. @xtiva2000 was present. 2 1 Link to comment Share on other sites More sharing options...

Thanks. I'm having interstage transformers in my custom 300b amp together with upgraded CMC style tube sockets, RCA and speaker posts. Built should be starting soon. 6 Link to comment Share on other sites More sharing options...
Odyssey Posted April 14, 2021 Share Posted April 14, 2021 In the early stage of my talk with Eric, it was propose that a special silver chassis and 3 chrome silver marzE transformers will be used but the matching choke is missing. On top of that, adding the black interstage transformers means it's not matching visually. So I've settled on a deeper chassis with silver front plate and black metal top plate. All transformers and choke will be timE and in black. This is what Eric has to say about Interstage transformers - When one considers the need to an upgrade to the existing coupling cap - one can either think about good caps like Mundorf Supreme Silver Oil or others, an alternative is to use I T ( Interstage Transformer) instead. I post a link here from Audio Note advertising their ITs and quote a paragraph extract from there: https://www.audionote.co.uk/interstage-transformers Replacing any coupling capacitor with a well designed and correctly matched driver or interstage transformer yields an almost shocking improvement in sound and should be tried to fully understand what a good wideband transformer has to offer. I do design and order 10 pieces of I T using Z11 core with interlaced winding 2 1 Link to comment Share on other sites More sharing options...

If I didn't already spend a bomb on my forth coming Swedish KT88 amp which incidentally I call 'Odyssey', I would have paid more attention on this 300b's appearance amp from Eric. Any other upgrades within reasonable means? For the KT88 amp, I went with Sowter UK transformers, Mundorf caps and Yamamoto's sockets and a snazzy chassis. Can't wait to see this in the flesh and to hear it. 1 Link to comment Share on other sites More sharing options...
