Ahh...if only I still had the Antique Sound Lab Exporer 805 poweramps I bought in 2005.

I had improved many parts substantially, including all-BlackGate caps in the frontend. They drove my Quad 989s...

...quite well.

Much equipment has passed thru my musicroom since then.

I place an order of Acme 805 tube an hour ago to compare with Cossor 805 tube which is better than stock 805 tube of LM 508 with more refined treble and deeper bass.


Cossor 805 is a good value.

https://www.hifi-amplifiers.com/en/...nd-vacuum-tubes-best-matched-pair-p-5126.html

I keep at least one spare tube just in case tube blow out.
I received Acme 805 tube yesterday.


Please note that both tube are made by same company Psvane.

Cossor valve was league above from stock tube with refined bass and deeper bass.


As soon I replaced Cossor Valve 805 with Acme 805 today, I noticed clear window of transparency and more details.

The soundstage got wider with 3-d holographic with clear window.

It seems like I had added pre amp since the change was so drastic.


It had not been burnt yet so it may be possible to change its sound for the next 2 weeks.

But the first impression is very positive.

I will keep you informed of the progress.

I also have pair of NOS United 805 tubes which I had not used yet.

After Acme got fully broken in, I will also compare it with NOS United.

I'd really like to see pictures of this system.
Smile...i really do not want to go off topic here...but as you asked...and we all wait...here you go...(I follow the concept that you can live in the chassis)

I wrote Rachel at Grant Fidelity about the new Acme series, looking at getting a pair of 2A3 tubes for my amps. They weren't available at that time. I'll see whether they are in stock yet. Been very happy with my current Psvane grey 2A3's - which have lasted 4 plus years.

GD Parts replaced the tubes without a question and before receiving the faulty ones. This time I made them send the tubes to a friend of a friend in China, who graciously agreed to bring them to me. So, no postal services crisis this time! Fingers crossed, he will be here mid January!

One of Psavne Acme 805 tube went bad with distortion with bias reaching only 50mA instead of 120mA after use of just 7 days.

I had tried to reach seller five times asking for replacement tube for 6 days.

But he did not respond to my message at all.

I had ordered tubes three times from him..

Previously, he used to respond to my inquiry within 2 days.




Now I do not have any faith in reliability of Psavne Acme tube which is pretty expensive.


I recommend you not to order any item from this terrible dealer.

I'm not ready to go as far as the above but there does seem to be a break in communication.
I have made several attempt's to communicate with my seller and none so far have been answered.

Mine are 2A3's and upon first try my experience was much like thomask. It sounded as if several veils were lifted and the sound was quite clear. I also noted that the bass was more solid than the tubes they replaced. Since then they have been very lackluster and even boring to listen to. My hope's are that surely they wouldn't sell tubes for such a price unless; a. mine are in some way faulty or b. like other Chinese tubes they take several hundred hours to reveal themselves. So, ..yawn, someone please wake me up when the real ride begins. In the meantime Psvane, we could all use some reassurance that we didn't just throw all our money into an empty rabbit hole. We want the good's.

Well, this sounds like my WE replica 274b experience...4-5 hours really wonderful and veils have been lifted...than boring...and few hundred hours later still. Stayed away from Psvane after that.

The dealer used to respond to my e-mail in two days.

But with claim of bad tube, he stopped responding to me at all..

Will Paypal be the best way to punish him?

It may be to early to judge the results. I would like to hear from someone that has 200 plus hour's. Also, I think Psvane should clear the air on the subject. Their neck's are in the proverbial noose on this one and I hope they recognize it. When your charging serious money then you better back what your selling. I wonder if the reason we're not hearing back from the seller is because they're waiting to hear back from Psvane. In the meantime I will keep breaking in the tubes.

Within 7days, the tube went bad with bias going up to only 50mA not 120mA as recommended.

I had tried to adjust it using bias meter in LM 508 with no use.

It went up to only 60mA.

The issue is not quality of sound but the reliability of tube and bad dealer support.

paypal is blocking the money for 30 days if I am not mistaken. Withing 30 days, they will bring back your money. You simply should state you got a defective unit. Defective is the key word which triggers the reimbursement process. You should raise the claim as soon as you realize the defect. Immediately. Otherwise you may run out of the time window.

GD sells them with 2 years warranty. Would be nice to understand what this is worth and if their process works.

Sorry to hear of your woes with the Acmes guys, sounding like some very troubling news. I hope things work out for the both of you and that also Kodomo’s replacements come through and actually prove their worth. Please keep us all updated and hoping things start turning around for how they perform.

Whit my previous Psvane 300B tubes I had similar experience but always after around 300 hours they turned out great and stabile.
I can’t speak for the new Acme serie of course but can imagine it must be the same.
I just ordered the WE300B plus and prepare myself for this 300 hours sometimes nice but most of the time boring music.
