Non-NOS component choices

[WhopperPlate]

Despite many companies exporting amps with the Dale RN65 resistors in them, as of today, they do still not appear to be RoHs compliant.

Aren’t the CMF series essentially more or less the same as the RN? Or is this a new “non magnetic” series different than usual? It’s listed new on Mouser . ROHS compliant.

Some very good info here. Applying this to currently available filter cap values, is there a consensus on suitable replacements for 300uF 350V filter caps? I see the #124 schematic listed here shows the filter cap node with two 300uF 350V caps in series for a 150 uF 700V net. If #102 has two 220uF 300V for a 110uF 600V outcome, perhaps this is suitable (and not blasphemous )? Thanks.

Close but not exact… ARS capacitors come in 270uf @ 450vdc radial can and 400vdc snap in …good caps with long life

Edit: they say they are out. Waiting on reply whether they will ever be in .

Edit: only available via bulk OEM orders

I remember way back, I was going to convert an old Fender Bassman to a dumble ODs (long story but it got cut short ) .

When I first saw the 300uf caps in the schematics and I couldn’t find any easy replacement , I was just gonna pack the doghouse on the fender with x6 100 uf spragues I had lying around.

Lol when I finally got around to building an ODS in a standard size chassis , remembering how much room they occupied I did think about stacking them like a trainwreck and making a glue castle, but I conceded at 220uf instead lol .

I still have those 6x sprague all glued together in a box somewhere I will reform and put ‘em to use eventually

It's no wonder that future versions (and maybe more with cloners) have resorted to radial capacitors for easier real estate, but they're not easy to find either.

Yes! Finding acceptable non nos components has practically always been an evolving dilemma

epcos, nichicon, kemet, UCC, Miec and so on, are making caps for 600V and are not expensive, time to go in this way..and use only 1 cap instead of 2 in series..

Or we can all pitch on a bulk order of the only axial cap left

what’s your fav there Bepone?

That’s a whopping 26 amplifiers ! Unless there’s a dud

until now for elcos massively /without any defect in 15 yrs UCC KMG, and often also popular F&T..
from 600V i didnt any, but it is a time now, how they are developing.. no sense to waste money in sprague/ 2 in series

[WhopperPlate]

For all the Draloric lovers , how do you feel about the current offerings?

It’s all a matter of what is considered a waste. I still can’t find any other capacitor that sounds exactly like a sprague…or a F&T for that matter . Neither are my personal favorite , but if that’s what you want to hear then that’s what you want to use. Good luck trying to find anything that sounds like the old Daly caps in Marshalls …

i shared this search list in another thread. Felt it was a good link to share here concerning finding modern available Carbon films for the B+ string .

Was thinking about other Non nos parts I have tried, and one interested power resistor were the Mills non inductive resistors . Expensive , but tank like ratings and it was pretty startling how swapping it into the b+ line determined the response of the amplifier .

Again , kinda like the takman effects on the signal path , I felt like I was under the magnifying glass . The amplifier slapped me around , felt like it had more output power because of the lack of distortion , not as bouncy and gainy, but the dimension was crazy . Not brittle , but wow was it loud in my ears and head . Stout was a word used to describe it .

That amp wasn’t mine, so it was changed to deliver a softer sound, but it’s something I want to try out again Soon.
