Interest Check: Plitron 300VA 18V Dual Secondary Standard Transformers

[jleaman]

Hi Jason, shipping from Toronto to Vancouver area is $16.95 for regular parcel and 41.85 for Xpedited Parcel (rate code 31). This is assuming you're in the V4-V7 postal code, but until things are finalized, I'm not going to calculate final postage, so don't quote me on these numbers (yet)

Thank's for the info, i'm looking to purchase 2

I called the 800 number for Plitron and the guy I talked to said that no tax was added for sales to the USA. As also shown on the attached picture from their web page.

Is it possible to order the 25+ units and have some shipped directly to the USA without the additional tax?

I don't mean to cause any problems, just checking into possibilities which might create more interest.

Hi Tom,

No problem with your post at all, the information is welcome.

Actually, I had already discussed this with Plitron and they have agreed to do a single large shipment to the US as part of this order. I didn't announce this yet because so far, there hasn't been enough interest from anywhere in particular to make it worthwhile.

I was planning on having the US recipient take care of all US orders via USPS (or is it UPS) $10 dollar flat-rate box to the rest of the US members.

 

[luvdunhill]

I could handle things from the US if need be. I know at least h_a (a member here) could vouch for me, as I recently collected a bunch of things for him.

USPS flat-rate would be an excellent way to save some money on the US side.

 

[twitchie]

I guess I should reiterate - this Group Buy is only supported by Plitron with regards to price for diyaudio members. They are not going to be handling payment, nor will they ship to all recipients.

So far here is the list of people who have shown interest (I) or potential (P) interest

(2) Twitchie(I) - Canada
(2) pchw(I) - USA
(2) JimT(I) - Canada
(2) Jaac(P) - Netherlands? (looking at the flag)
(1) hc167(I) - USA
(2) rdk845(I) - USA
(1) KT(I) - USA
(2) luvdunhill(I) - USA
(3) jinkslynx(I) - Norway? (looking at the flag)
(2) Dennis Hui(I) - Canada
(2) jleaman(I) - Canada

That puts us potentially at 21 so far.

I am interested in two transformers. Thanks

I am interested in two transformers delivered to CA, USA.
Thanks

 

[tommak]

Please add me to the list for one.

Thank you!

I too would be interested in 1 or 2, I am just starting to read up on building one of these First Watt projects, either the F3/ZV9 or an F4.

Location: DE, USA

Thanks,

[gabkw]

Hi twitchie. I could also be interested in a couple transformers. Plitron makes some of the best power transformers out there and prices aren't about to go down anytime soon. What is the next quantity for another price break? I think we could probably get 50 easy with the VA rating and secondary voltage chosen. I would have no problem being a US distributor for this since there are quite a number of folks in the US that are interested. That would cut down a bit on cost since you could send one big package over the border. That sucker will sure be heavy though!

EDIT: I didn't see that luvdunhill volunteered before me! If he does not want to do it I would be fine doing it as well.

 

[greyhorse]

Count me in for 2 as well twitchie. This sounds like a great way to get started on a pair of balanced mono F4s.

plitron transformer group buy.

I'd be interested in two of the dual 18 v secondary transformers... let me know if this works- Thanks in advance-

Hey Twitchie--

I don't want to be a party pooper, but maybe 300VA is a bit small???--at least if you are using it for stereo amp.

I just rebuilt a mini-aleph (stereo) with a 250VA avel, and I have a lot of mechanical buzz (well, not really a lot, but it is audible). and -- The bias current is only 1 amp per output device.

Maybe it might be worth the few extra bucks for a 400VA??

Just my 2 cents, whatever route you go, lets hope for no noise!!

JupiterJune - I looked at the larger transformer as well, but it would then become a custom order since 18V is not a standard offering for their 400VA units. The price jump to 400VA over 300VA is also quite significant, but the biggest peace of mind for using the 300VA comes from Nelson Pass himself in the F4 thread:

you see various ratings for continuous vs short term and of course
this has to be taken with ambient temperature, frequency, and
power factor. When in doubt, Plitron."

BWRX - Your offer is appreciated as well. I will need to talk to luvdunhill to see where he's located, but you being in Pennsylvania may make it cheaper (for everyone) to ship to you. I'll have to check with Plitron on their shipping rate as well.

I never thought we would approach the 50 unit mark, but I'll see if we can get the same discount applied.

the aleph mini i think is a little higher than 1.0amp, its like 1.3ish i think.

The more Va, the less effort the transformer has to do

Are you sure your amplifier and transformer are working correctly?
A 250VA transformer should be more than enough for an Aleph-Mini. I built mine using a 160VA C-core, and had no issues with mechanical hum/buzz.
