You definitely need a round base one 😁

Yes I'm running the TU-8900 + Amorphous output transformers and have paired with Sen hd 800 and Hifiman he6 using a Chord Dave front end both are really superb out of the 8900 fwiw it's also one of the quietest amps I've owned tube or ss. Had the Sen 800 paired up with a hot rodded Bottlehead...

Probably the demand for such new tube offerings is going to be driven by amp manufacturers themselves to be included when they sell a new amp. They will purchase in baulk with a substantial discount from the retail price the public sees.

The warranty sucks it's crazy that you can buy a old nos tube from the 50 and 60 that was made with really old technology yet it still works and sounds great I've some that have been used for 5+ years with zero issues. Yet a modern tube made with "cutting edge engineering" gets a misery three...

I had tube fail on my valve preamp which killed one of my he6 drivers. I also had superb customer support from hifiman.

Beautiful build of the Crackatwoa it's pretty rare to see someone go the extra mile and do volume control panel as well 👏 👏

I found a internal pic it looked like 1uf which would make them to expensive as the H5 needs four. If 0.1uf it might have been a option I would guess Eufonika gets a good deal on Milflex as they are also manufactured in Poland.

Does anyone know the uf value and voltage rating of the output capacitors in the H5 the ones that are used in the milflex version. I ask as I see Milflex have released a new silver foil capacitor range. Edit found the answer

No shipping to UK probably have to buy through hifi collective with a big mark up in price 😒 was think a pair of the 0.1uf for my Elekit tu-8900

Fwiw I had some unexpected results from powering some small DIY desk top speakers directly from the mojo. This from a few years back I was messing around and hooked up the mojo direct to some small desktop speakers I had built the misses came over and sat down to listen (must be sounding nice)...

I've brought several electrical components from Ukraine eBay sellers in the past with shipping to the UK and have never had any issues. Shipping often takes longer than expected but that's probably to be expected.

Have owned a Dave for four years now I do think it's a great bit of kit but I also enjoy listening to my car radio which is definitely not hifi 😁 Striving for High fidelity is no guarantee of enjoyment and I've yet to hear a stereo system that comes close to sitting a 3 or 4 metres away from a...

Thanks for your feedback is that with the 8600 or 8900?

Any feedback out there on running the HiFi Man HE1000 V2 Stealth on a the TU-8600 or 8900?

That was pretty much what I was getting at the hd800 are enjoyable on the Crack but capable of a lot more than the Crack is able to deliver move up to Mainline and it takes the hd800 to whole different level if you have a good front end.

Just an point of view HD 800 on a Crack imo does sound nice particularly if you have a few mods and some choice tubes. The Cravat is ultimately the Crack is going to be a bottle neck and limit what the HD800 is capable of delivering particularly in soundstage and resolution.

It's a GEC 6080 the the Z gives it away

I remember on the Bottlehead forum when you built the Sex with those giant Ampohm output capacitors and Goldpoint attenuator. It was an amazing build. I still have my Sex amp as well its probably the sweet spot of the Bottleheads headphone amps imo

That is a fantastic idea

I asked Google looks like Cinemag https://ecp-consolidated-productions-llc.square.site/product/headphone-amplifier-parafeed-transformers-pair-/5?cs=true&cst=custom Solid high nickel core output transformers for headphone amplifiers. These transformers are made for us by Cinemag and feature a...

Always fancied building a torpedo. I'm not sure if I rember correctly but think there was a nickel output transformer version at one point.

Have it paired with an original Russian Melz 1578 (6sn7) the real 1578 has five holes punched in the sides of the plates Here they are glowing in the dark. Sounds fabulous Internet pic as the wife is asleep and I'm not turning on the light 😁

Copy and paste from the old cached Bottlehead forum The 7236 is a computer rated 5998A but should sonically sound similar to the 5998. This specific 7236 has zirconium coated grey box plates. Similar to the 5998 sound abeit more linear, tighter bass and more dynamic. Basically a "faster and...

Crikey no posts since October! Was having a root around looking for something else and in amongst some boxes of tubes I found a couple of CETRON 7236 tubes 😁 It's the first time I have listened to one in a amp sounding very nice it is to right up there sonics wise with some of the more well...
