How can I punish this Chinese audio dealer


I ordered three pairs of tubes from him last year.

The dealer used to respond to my e-mail within 2 days with fast shipping.

The Psavne Acme 805 tube went bad after 7 days of use.


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

I sent him 6 e-mail within 7 days.


Will Paypal refund be the best way to punish him?

I received Acme 805 tube yesterday.

PSVANE Acme Serie 805 Vacuum Tube High-end tube Be


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.

It seem like I had inserted pre amp since the change was so drastic.

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



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 had exchanged e-mail with dealer.

His virus program filtered any e mail with enclosed files to spam mails

The dealer will ship new replacement 805 Acme tube on Monday.

I will update the situation after I receive the 805 Acme tube.

In most case, Paypal will give enough protection.
I have been a tube guy for the last 15 years and have had too much bitter lessons in buying vintage tubes.  Never trust NOS indeed, especially you plan to use them on SET amps.  You simply cannot get a real matched pair.  Not to mention how much premium you have to pay for a pair of WE 300B, 274b, RCA211, etc.. you will never have a peace of mind in buying vintage tubes imho. 
I must agree. NOS tubes are hit or miss even from dealers I respect. Fortunately new tubes are getting better and better. Just purchased a pair of kt77 power tubes from US manufacturer Walthen. Looking forward to trying these out. Reviews sound promising.
