labjr, send me an email so that I can send you a request for $40 deposit via Paypal.
pedrop, I will have to up the order from Plitron again. If you are certain you want the transformer, I will also need a $40 deposit from you to secure the transformer. Send me an email so that I can send you the Paypal request too.

Out of curiosity, why haven't any of you considered SumR? They do full shielding and encapsulation and custom winding just like Plitron, but they're less expensive and no minimum order.
They are located in Canada so shipping is a little slower, but that's about the only drawback I've experienced.

I used a SumR 80VA 30V transformer for the AMB ß22 preamp/headphone amp that I made last year. After replacing the unshielded tranny I was using with the SumR, the 60Hz hum in sensitive headphones disappeared. I was pleased.
I have two more on the way for the AMB ß24 that I'll be building this year.
So, I personally recommend the transformers from this company when shielded transformers are needed. Otherwise I generally use Avel-Lindberg.

I am in the process of upping my order with Plitron to a total of 10 transformers. So that means 2 are left unspoken for. Anyone may contact me to reserve one ($40 deposit required).
Here's what we have so far:
CORT (me) 2
Teabag 2
Samoloko 1+
Daniel D. 1
Collin R. 1
Labjr 1
My hat is off to people who do larger group buys. It's a logistical challenge. I am definitely closing this group buy after the 10 transformers are spoke for.
P.S. Never heard of SumR either.

Re: Custom Magnetics
I am considering ordering two R-Core 500VA 2 X 18V secondaries as samples.
If there is one or two people who may want to borrow to listen in circuit or purchase one sight unseen let me know.
I can then listen test myself - differences in Antek, Plitron and US Magnetics R-Core. Anyone I trust well or has test equipment will get biased and preferential treatment.
It's probably a good time to have them around, as people have their FW boards in various stages or clip leads, smoke and chassis building operation.
If the listening test turn out exceptional, then a lot more could be ordered for a little more than a Plitron.

Tea-Bag said:I recieved a qoute from custom magnetics.
I have no experience with them, but they seem to be the only people in the USA with R-Core experience.
I am not inclined to order these considering the price.
the reality is, you could buy two Plitrons or several Antek's for the prototype price, and we may not want to order these in quantity given they may measure and sound aweful.
I was hoping for a inexpensive proto price to test.
Hello Mike,
Thank you very much for the opportunity to quote on a dual 500VA transformer in R-core or in a toroidal package. We have reviewed your preliminary specifications and it looks the toroidal package is comparatively cheaper than R-core. We can build in either package. We are pleased to present you with following budgetary quote:
Part # Quantity Unit Price with Toroid Unit Price with R-core
TBD 2 Pieces Samples $150.00 $190.00
25 Pieces $90.00 $110.00
50 Pieces $80.00 $95.00
We can provide you samples for qualification in 6 weeks ARO. Our start up production lead-time is 12 weeks ARO, FOB Chicago, IL and terms are net 30 days with approved credit.

Re: Re: Custom Magnetics
I just figured Papa designed the F5 as a whole and the synergy of the parts including the Plitron sound good together.
I think there's a balancing act played to get the sound just right. I trust his golden ear since he's been sucessfully doing this for four decades or more.
There's also the possibility that there's a point of diminishing returns with more expensive parts.

Just wait til you have to carry them all back to the post office ...
I just went to Plitron today actually to pick up some surplus transformers (4x24v, 2x18V 234V input and a 2x36V). It looks like the sales dept has all changed since we did the last GB.
The 4x24V says 'Wadia' on it, so I guess we're in good company with these transformers
Good Luck and make sure to post pictures of the stuff you build with these.
Pedrop, I think I've created a link to a Paypal button to make deposit(s) on the last two remaining Plitron transformers from my group buy. Try this link and see if it works.
There is one transformer order left on this GB available for purchase. I've confirmed with Plitron a total quantity of 10 pieces (plus Samoloko's surplus transformer) and won't reopen the order. See my link above to make a deposit for the last availble unit. The transformer price for everyone will be $85.36 each plus shipping to you. I've been taking $40 deposits from US buyers and near full price deposits from international buyers. (Pedrop, you made a $47 deposit--your extra $7 will be applied to your balance).
Here's a list of deposits so far:
CORT (me) 2
Teabag 2
Samoloko 1+Plitron's surplus unit
Daniel D. 1
Collin R. 1
Labjr 1
Pedrop 1
Maybe Plitron will surprise us and deliver sooner than expected, but I am anticipating 3 weeks for the transformers to arrive at my house, then another few days to a week for the pieces to be delivered to their final destinations.
Thanks to all.

Possible 240V to 2x18V Plitron
Hey guys,
In case anyone came too late to this thread to get in on the group buy but still wants a Plitron, check this out. I was looking through the Surplus section of Plitron's website and noticed the following, for 240V users:
Custom Power Transformer
234V primary (1 pair of wires only)
2 x 18 V secondaries (2 pair wires)
300VA rating
Get this: $46 CDN plus shipping.
So, if unlike me you can use 240V primary, check this link out:
http://www.plitron.com/shopping/shopexd.asp?id=652
I think they only have one, but I didn't look too far into it. I have no affiliation with Plitron, of course.
Best,
Collin
