It looks promising and very versatile, but I hope this is not the final faceplate...

Thanks. Will be watching this closely. Have wanted to make the jump to build a full fledged tube amp and I've been impressed by the Elekit package.

you can view 8800 in Toronto show

Viktor,

This looks great! What is the cost of the Lunhaul upgrade? Are there capacitor upgrade options? I'm very excited about this.

 

[gavinb]

Cost for OPT upgrade?

Will it accomodate a TDK pot?

 

[vkung]

The Lundhal + PCB + HV + Hardware is $645
YOU can use ALPS R27 and TKD with conversion PCB

I'm waiting for this to be released, especially with the Lundall transformer upgrades. I have a TU-8200 I built years ago and it just doesn't have quite enough oomph for my liking. This looks much like a TU-8200 on steroids.


@vkung - Is there a list I can get on to order one as soon as they're available?

 

[vkung]

please send me an email
the amp will release in late October

 

[vkung]

I have just received the pre production TU-8800. It is no doubt... another wonderful design from Mr Fujita. The tastes are very different...

 

[paczeltf]

Silver faceplate, please...

 

[vkung]

THIS IS IT

 

[Steve Morley]

Error on label?

Victor,

I think there might be an error on the tube label, see attached. The 7591 (circled in red) is not pin compatible with the other tubes. Shouldn't this be 7581?

Regards, Steve

 

[vkung]

I have no personal experience with any 7591 tubes.

 

[Steve Morley]

With all due respect

to you and especially Mr. Fujita, the 7591 has a different pin-out than almost all other power tubes. Plugging a 7591 into an amp that's stet up for 6V6, 6L6, EL34 etc. could do damage. See the attached basing diagrams.

With regards, Steve

 

[kingtaco]

Hi Victor,


I believe Steve is correct about the pin compatibility. According to [1], pin 5 on 7591 is k,g3 and according to [2], pin 5 on KT-88 is g1. I don't know if 7581 [3] was intended, but does seem to be pin compatible.



[1] - 7591, Tube 7591; Rohre 7591 ID3729, Beam Power Tube
[2] - KT 88, Tube KT88; Rohre KT 88 ID19153, Beam Power Tube
[3] - 7581, Tube 7581; Rohre 7581 ID6179, Beam Power Tube

 

[vkung]

thank you for your info
I will check with Mr Fujita

FYI I run 7581A tubes in my TU-8200
