Hi all, new to elekit but would anyone know why they moved from external switches back to pcb jumpers with the 8200r update?

More importantly would anyone who has assembled on think there is a way to extend the headphone power selector to the back panel via dip switches or similar?

I'm considering one of these for a headphone amp and have 13ohm and 300ohm headphones but see myself only using it for one or the other if this is hidden.

Thankyou

I am with you on this one. I love the sound (re)produced by the TU-8200R, but the jumper situation is clearly inconvenient. I keep the impedance setting at “low” and use the amp for my low-Z ( < 100 ohms) hp. My high-Z hp are driven by an OTL Woo WA3. (I did not build the amp; it was built by an EE).

Thankyou,

Did you ever run it in high/med mode and compare the 8200 to your OtL?

I'm in the market for a single tube amp to do a bit of everything.

I might hitup a local builder to see what they can to make output power selection easier.

My guess is hiding it on the pcb ensures power is cut before making a change.

Hi Barbz, good to see you here and good to hear you're about to get a 8200R for yourself.

I'm not sure what mine is set to. I've not changed it since buying it over. Although I did open up the case to change from UL to triode and to UL again twice. Even this would have been nice to have an external switch. Now mine is left in UL mode.

I did in fact compare the 8200 “high”-Z mode with the WA3 for ZMF Auteur, Beyer DT1770, Senn HD600 (Custom Cans UK mod) and felt that there was a touch more “there-ness” with the WA3. Was that OTL, maybe? Was that the WE 421a with Amperex PQ 7316, maybe?

A friend is bringing over a Mchanson amp that can run 6L6GC, KT77, KT88, KT150, EL34 over soon for me to compare with the Elekit TU-8200. Suddenly there's a proliferation of amps that can run these tubes. Choices are always good.

It's a model similar to this

I'm really interested to hear about this, ive been talking to your friend and Eric about these builds. Make sure they bring the 300b amp over too!

Oh no he does not have the 300b amp with him but I’ll get to hear it another day.

I will see what Mchanson amp Dennis has later because I will be going to his place after I have audition the KT150 at my place... to get a Mullard gz34.

It’s going to be an eventful Sunday.

Thanks very much for your help, l am going to get one if that's the case

Western Electric is making 300B tubes again so it will be nice to hear a NOS vs. NEW

300b tubes are not in my radar now as I'm still chasing KT88, EL34 NOS. Plenty to keep my wallet occupied.

My dalliance with Mcchanson KT150 amp and my impression of it vs Elekit TU-8200 going from memory.

With the tubes you've tried in the 8200 to date do you have a favorite type (kt66/77/88/el34) ?

I've a lot of favourites amongst the NOS tubes in the order of preference but they are very close, separated by a hair's breath:-

Telefunfen EL12 spez with adapter
GEC KT66
Philips Miniwatt 6CA7 tie with EFT EL34. In fact these 2 are so close to the GEC KT66 in terms of preference, I would put them all three on the same level.

Next comes the current production tubes which are very good if you didn't listen to the NOS tubes:-
Genalex Gold Lion KT77
Genalex Gold Lion KT88
Electric Harmonix 6L6GC - this is the stock power tube.

Drivers that I have in order of preference:-
Brimar 12au7 long plates - there is a difference between the long plates and just the normal Brimar 12au7 - in terms of SQ and price.
Philips Miniwatt 12au7 - nice warm tone
Sylvania 12au7
Psvane 12au7
Gold Lion 12au7

I have Amperex 12au7 and Tung Sol 1960s 12au7 coming later at $400 a pair. I was assured by my astute seller that these will clean your ears and internal organs.

I have GEC KT77 used coming later. Also coming later is the Tung Sol 1960s 6550. Much much later will also come the money sucking GEC KT88 NOS brand new. Canadian maple leaf and Radiotron 807 have been purchased.

For Odyssey, I have tubes set aside additionally for my. Brimar 12ax7 that I was told is older than Methuselah. Mullard 12at7 with gold pins that is rarer than the Queens's corgi. 596 rectifier that is next in line to the throne of USA.... was going to say England but these are JAN USAF so it was made for the United States Air Force. F16s use them when they were F1s. Philco 5u4g, Mullard 5u4g, 5u4g from West Germany.

Alright I'll take a breather. It's getting tiring just by typing all these !!!

Thankyou,

I have half a dozen brimar 12au7 long plates so that should keep me going for a while.

Eying off a set of mullard el34's....I should probably buy the amp first
