SimpleSE R17_R27 selection

Well, many of us here have asked.......but with Edcor you can have any color you want as long as it's blue......

I have purchased the bare endbells from them; they are cheap $$ and work fine although you still need to paint or powdercoat them. I've bought some of these endbells to retrofit onto 200 series Hammand transformers, they bolted right up. BTW, the blue powder coating can be removed with paint stripper.

Edcor used to have a $20 NRE fee for custom orders, but IIRC it's now $40. The customs end up as std product once someone orders and pays the NRE. The XPWR-131 is an example, Rknize ordered it custom for use in the Tubelab SE with 45's or 300B tubes and many of us have since purchased it stock off of the Edcor site.

The transformers are built to order, so that equates to a 5 week lead time typically, sometimes a little more or less. So placing your order sooner rather than later makes sense. I once asked Phyllis at Edcor why they don't stock popular transformers and she laughed, stating that they can barely keep up with the orders.

When did Edcor go "all Ford Model T" on their customers? Guess Henry Ford would be proud, but, of course he liked all the colours mixed together into black.



I have emailed Edcor support, just in case they had a good holiday and are feeling something other than festive gentian blue. Maybe neon green...or Addams Family midnight flat black. Suppose I could always get some rectangular covers like those from K&K, Lundahl or "Cubes for Tubes" in Denmark.

I have a pair of very early vintage Edcor OPT's. Back then they were only one color, bright METALLIC blue. It was the same color as a "Pimp my Ride" Cadillac that used to hang out in the neighborhood.

They can be seen in this photo, and yes that is a working amp.

It's just one of their little things...part of their trademark/identity I guess. The powder coating is tough to remove so I would pickup the raw bells that they offer if you find it offensive. Also, their core sizes are fairly standard. For example, the bells from a 193J Hammond choke fit one of my Edcor trannys perfectly.

That IS a shocking blue...

Someone at Edcor must love gentian blue is all I can figure...

Suprise of surprises...Edcor said 'no'. However, they did say "I'm sorry..." Guess I'll either learn to like Edcor Blue or get some covers or build a really deep chassis to hide them away. I really want to showcase the tubes, not so much the iron.

On the R17/R27 front, staying on topic, the selector switch (double deck, 1 pole per deck) is the way to go after some thought.

The scheme incorporates the advice in this thread, with a main "protective" R17/R27 soldered onto the SimpleSE board (e.g. the stock 560R). In parallel with each is then a 1k unit in series to the input of the selector, followed by a variety of stock values at the switch positions.

Maybe I could use all the convective and radiative heat from this resistor selector to cook off the Edcor Blue...hmmm.

It's a small price to pay given the quality you are getting for the price of their OPTs. I was so pumped when I found out about these guys from this forum, especially how they can so easily make custom power transformer designs and are willing do to so for the DIYer. No more scrolling back and forth through Hammond's website trying to find a workable solution only to have it overheat and be way out of spec in the end.

For the switch, it doesn't have to be double-deck. It just needs to have two poles. For 6 or fewer positions, they can fit two poles on one deck. Just FYI if you are searching on Mouser or wherever. Mine is 2P6T single deck:
