attached, now, cutting and drilling time. Tim, have you ever used those Russian PIO caps in amp build?

The k40s are great

sinner · Post by **sinner** » 22 Nov 2011, 14:00

Those are the green ones?

diagrammatiks · Post by **diagrammatiks** » 22 Nov 2011, 14:57

the k40y are the metal encased ones.

the k42y are the green expoxied ones.

I think they are two different dielectrics.

The hifi guys generally review the k40y as being the better of the two.

I find the silver ones a bit sturdier and easier to work with.

The K42Y-9 is the metalized version.

The dielectric is the same but applied differently. IIRC, instead of alternating separate layers of paper and foil, the metalized cap has the foil adhered directly to one side of the paper.

Metalized caps are smaller and they can "self-heal" making their more tolerant of voltage peaks.

The K40Y-9 also come in a coated version, which is brown.

Nah, I'm pretty anti-mojo when it comes to amps. I used Jupiter caps in my Tweed mainly just cuz they were big, but not too big, small caps just look weird on a low part count amp. I wanted to board to fill the chassis. I used the Holy Grail caps to get the old school orange cap look. When I do the redux I'll prolly use mojo's dijon caps and F&T electros, not for sound, simply because there sized nice, made well and are priced right. Really, I just pick stuff that looks good, because I like to see pretty guts whenever I open any of my stuff up!

What are you gonna use for Transformers? Speaker selection is also hhhhhhuge with this amp.

if you're just going for size the ero/vishay kt axial series would do just as well.

I love my pretty vintage and otherwise fancy parts but the idea of a repro mylar capacitor for tone is just...

something like that or maybe

sinner · Post by **sinner** » 22 Nov 2011, 19:14

I don't know, ClassicTone have right reputation when it comes to fender clones... Those trannies are also priced right, I had nearly heart attack when Chris Merren prized me for my 12xxx SL... I think I'll do just the preamp board for now, and I'll stop there. I'm kinda excited to make jtm45 right now, I just cut the board and drilled holes, tomorrow turret time

I just find difficult to focus on one project only.

The ERO's are alright size wise. I agree on 'repro mylars for tone' being bullshit. I used the Jupiter's just cuz they were huge compared to EROs, Mallory, yadda yadda. I wanted to get the old huge Astron look. I don't believe the hype on the sound. Same with the dijon's, I don't use em cuz of the hype around the sound, I like em cuz there a decent quality, priced good, look cute and easy to nab as I usually grab other parts from Mojotone at the same time. That's kinda my feelings on the PIO caps in amps too, they're not gonna improve anything soundwise, but there seems to be a lot of hype around em. I've yet to hear dramatic differences between all the types. The only time I've heard differences is when I'd change a value. It's all about sex appeal to me!

Pawel, have you checked out Heyboer's at all? I think mojotone sells export. They make really good stuff.

sinner · Post by **sinner** » 23 Nov 2011, 06:43

I know Heyboer's, no idea about the price range... There is a Germany \based transformer maker who do great trannies, but he don't do fenders, just slo/marshall/hiwatt. I forgot the name of him, IT Transformers, TI transformers... (Germany doodz, help!) I have it somewhare bookmarket...

For coupling caps I pretty much stick to Mallory 150's in my amps. I have tried Mojo Dijons and thought they were ok, and Sozo's too but they took forever to break in and then were not really different sounding than 150's besides the price. If you really want to spend money on caps you can get these:

I spend alot more time finding pretty caps for pedals because you are gonna see the guts of a pedal alot more often. At the same time I will shell out the money for high quality filter caps, gotta get the best there!

I think SoZo is out of bussines, or trying to be. I emailed them 8 months ago few times asking for Royals, and no replay ever since

Wow, that is sad. I looked at a bunch of threads on different forums concerning the shipping times and lack of communication. Looks like people are getting their orders mostly, but it is taking a long time. Maybe they are concentrating on commercial accounts and not the small individual orders. I think they supply Bogner and 65 Amps, that could mean alot of volume of product.
Angela instruments has rolled out it's own version of "50's style" tin foil caps. They look nice but I think you could more easily get the same thing in Europe just buying SCR's. I doub't they did anything different besides printing the Angela logo on them.

Mallory 150's are always a good bet, especially on larger circuits when rooms tight. I've used Sozo's here and there but I definitely don't think their worth the price. Especially those blue ones. I remember when the Jupiter Red tin-foil caps came out too, some companies are really milking it. I've looked at those Angela tin-foil caps before. Looked interesting but just not worth the price. That shit adds up so fast. I've seen amps that used all Jensen PIO caps (the 20 dollar ones) and it blows my mind. Like I said before, I've never ever really heard a dramatic difference between different capacitors. I guess another factor I look for is size to fit existing boards. I don't like having long ass leads everywhere.

Timbo, what do you like for filter caps? I've pretty much settled on F&T's.

sinner · Post by **sinner** » 23 Nov 2011, 19:04

I hope they'll be fine, I can't really find suitable alternative for 100uF high voltages...

I like the black ones

I think the few times I ordered sozo caps I got em indirectly. Maybe shop around. The 100u for the plexi? I can't remember if I used Sozo or F&T when I recapped my Hiwatt.

I use F&T's for filter caps too, gave up on Sprague Atoms quite awhile ago. F&T's always seem a little more compact which is nice if you are adding axial filter caps in an amp that had a cap can to start with and you want to try and hide a few in the old cap can.

this german site has special order f and t's that are higher voltage rated.

good stuff.

seems like plenty of people love sozos so i'll keep mah mouth shut.

I've googled peg124's in my country (Poland), it seems they have all values I need, I'll give them a try and report back

http://rseim.pl/index.phtml?k=92485351& ... e36d9018ac

I never heard about this webshop before, so I can't comment now. I'll ask them do they ship internationally as well..

As per Sozo. I'm just starting with amps so I can't really comment, I've use them in few fx builds, but IMO they have no more mojo than TAD mustards, or those yellow Vishay/Ero caps.

Fell free to speak up, this is what the forum is all about
