Help returning an Allnic H1500 SE II phono stage

Have you tried the importer or a US retailer?  I am using the 3000 phono stage and retubed once.   

I have the H3000- your best bet, depending on where in the world you are located, is to contact the authorized factory/distributors. Albert Porter is US (maybe all of North America). I bought the oddball tubes for the H3000 on Ebay as well and have some back ups- also got a complete set from the factory. My recollection was that some of the tubes I got from eBay, branded Mullard, made in Great Britain on the glass, were actually made by Amperex in the U.S. It wasn't that the seller was selling bogus product- apparently, tube companies shared workload in the past- and did this without regard to what we think of today as correct provenance of the tubes--they were pretty much fungible parts. And, I was informed that the Siemens and Mullards supplied by the factory for the H3000 were essentially the same tube. The rectifier makes a huge difference- and there, you can go to the open market; some other Allnic owners may weigh in but my sense is that you aren't going to get as much out of rolling the tubes on the audio circuit as you will the rectifier.  Dunno if that helps. Albert is pretty regularly on this board, and easy to find on the Net. (and a nice guy to boot, though he may be off to an audio show right now). 

Thanks guys I am in Houston and Albert is in Dallas, have been in contact with him in the past and will probably just get him to get me a set from the factory. Have replaced the rectifier tube with a Phillips/Holland, had to alter the socket orientation a tad to get it to fit but wow what a difference. Just wanted to air this out on the forum and see what comes of it.
