Looks interesting and very tempting.

I wonder if there will be an octal version?

Its very new, but some are probably in the process building it now
But why should it be very different from his other options, which are very popular
But hard to imagine they would be better
But we know that different supply may make a significant differense

Im sure it wont be long before Broskie have them stocked again

Slightly better or slightly worse than the original Aikido, the point of is that it's easy - all in one!
For a newstarter in valve preamps, that's the important point. And this all-in-one Aikido certainly has a selling point

Indeed very well done!

I am looking forward to this.

I hate to bump an old thread, but since I have a question on it...might as well.

Has anyone built one of these (specifically thinking the octal version)?

I noticed there's a bunch of parts that can be ordered with the PCB...any advice in choosing which options? I'd like to go with metal-film resistors, and I assume the most expensive caps (RTI) offered are worth it?

Thanks in advance

Glowbug,

I am seriously considering the Aikido octal all-in-one kit complete with Russian-made Tung-Sol 6SN7 tubes, RTI coupling caps, metal film resistors and selector switch. This is a bargain and takes a lot of the guesswork out for assembling a decent power supply for the octal amp configuration. I would also recommend Vampire CM1F RCA connectors and a decent SMD stepped attenuator that can be purchased via eBay.

Hi Glowbug, rhing,
I'm using the old Aikido Octal version (not all in one because I purchased it 2 years ago) with Russian made Tungsol 6SN7 and very pleased with it. Had I purchased it now I would go for all in one version because it saves a lot of time and effort in trying to collect parts and build yourself a PSU especially if you are a newbie.

I think you can choose metal film for lowest noise and RTI cap is a good option

If you want even better sound but with a higher cost (of course ) then go with the octal dual mono and separate regulators for each channel.

Default Aikido All-In-One vs Dual Mono Octal Kit

I am trying to decide between the All-in-one or the Dual Mono Octal Aikido kit. Is there a sonic difference between the All-in-one vs Dual Mono if I use just ONE PSU for BOTH channels?

How will the sound improve having separate regulators for EACH channel with the Dual Mono kit? Channel separation, clarity, dynamics - not sure?... Do I need another power transformer too?...


Proposed Power Supply:
-Hammond 270BX
-Mullard/RCA 5U4-GB
-CLCLCRC: 20uF, 20H (Hammond 193C), 50uF, 10H (Hammond 158M), 50uF, 300R, 50uF. All PSU caps are 440V ASC Motor Run Capacitors.

Thanks
