LaChapelle 583s is around $775 on Reverb.com and I know a lot of guys in town that will grab that pre before a V72 for vox and acoustic. They sound great and are silky smooth. There is a MK1 and a MK2, most everyone I know has the MK1.

There is a MK1 and a MK2, most everyone I know has the MK1. I was considering a LaChapelle but then Sound Skulptor released the MP566. On the surface it appears similar to the LaChapelle 583s MK2 but I suspect it may be a bit more colored as it doesn't use Jensen transformers.

A few of my non-500 series Sound Skulptor pres. How do you find these? I believe these are supposed to be cleaner than the SS 500 series tube pre.

Other than Coil Audio and myself, has anyone here used an RCA BA-2, Collins 6Q-1, or Gates SA-70?

aamicrophones, i know now I would be very interested in your tak on the RED47 preamps. I have a Tabfunkenwerk V78M and it's great.

I had a pair of the 583s's. They never did anything for me really. Boring. Ended up selling them. I know some rave about them..... I wonder if it's the difference in tubes. AT any rate, it was just too clean, and I might as well have been using a solid state pre.

I like the V78's I have re-built for folks better than the V72 but the V78 has at least 7 capacitors in the audio chain and the Redd47 has 4 capacitors. This is a case where less is more in my book.
The Red circuit is quite elegant with a fat/present sound.
I have used an RCA BA-2 back in the 90's and it sounded really warm and smooth sounding. I probably have some 6J1 tubes kicking around here somewhere I would give away to a good home.
I had a 8- Altec 459a tube preamps in a rack back in the 70's. We ended up selling them as they sounded amazing but they heated up the control room too much as we hadn't anticipated the gear creating so much heat.
When we built Ocean "proper" in 1979 we use a 1 ton air conditioner for the control room and a 2 ton for the studio. Each control room and each studio had their own air conditioners.
Cheers, Dave

2cents (if you diy at all or know a tech) If EmRR still has his Gates SA-70 pair for sale over in the classifieds (for $700 ?) we'd absolutely sell you one of our fancy 2u rackmount PSU to power it - that leaves you with quite a bit leftover in your budget to rack the pres in a nice chassis with cool knobs n such that would last more than 50 years. Id say we could rack it but theres too much on the work platter currently (i.e. single channel CA-70 and EQ that will be in that 1k budget range <shakes fist to the sky emoji> Those SA-70s are light years ahead of anything mentioned so far in tone and density - and at that price per channel, its kind of a no brainer - Again, only If you have the means .... Coil Audio YEAH! When is that thing coming?? CA70 SC

I used the Diz d4 for a few years while saving for the Chandler. Never had any issues with it. Good sound. At your price limit I think it would be worth an audition. When I sold it I lost like $50. For almost 2 years of use. Not bad.

We have two fitted with NOS Mullard 12AT7's. The low/medium gain settings are quite clean but there's some richness the tone which I really like. Using the high gain setting the tone gets richer and more harmonically saturated as you crank the gain not unlike driving a good tube compressor. I'm getting ready to order some sound skulptor stuff to build for someone else, so I might just add an MP566 to the order since the incremental shipping cost is like $5. I basically just want to hear what it sounds like, and then it'll go on the classifieds here, if anyone wants it. How are the stock tubes? I actually have a NOS Mullard 12AT7 in a C12 clone, so I guess I could pilfer that just for testing purposes.

I have used the 583 a lot and I love its high-voltage tone! It has a sweet, warm soft but detailed sound. I love the point at which it naturally adds tube compression. Scott makes great gear.
I have been using the Coil's a lot and they are the thickest most punchy mic amps on the block!!!!!

Plus any parallel between CA-70 and SA-70. Anyone can send me 6J7's anytime they want! Eight 459A's would be a good winter addition, I think they are like 35mA 300VDC apiece, with 6W output capability. I got rid of a rack of Langevin 117A's for the same reason, even though they sounded amazing. Eight 6V6's, so like 4 Stalevel turned on at all times.

Coil Audio YEAH! When is that thing coming?? CA70 SC Its looking like July at this point, we're having the faceplates etched and filled with an epoxy paint to really make these little guys pop- so thats a bit of an undertaking. Still on the fence about a summer NAMM appearance/booth, we might just come down to hang out and drink all of Sputniks booze.

But if you have a Mullard 12AT7 then you can compare.

I had a 8- Altec 459a tube preamps in a rack back in the 70's. We ended up selling them as they sounded amazing but they heated up the control room too much as we hadn't anticipated the gear creating so much heat. The Altec's had 3 tubes in each module drawing 1.2 amps total to light the filaments X 8 = 9.6 amps X 6.3v = 60.5 watts just from the filament supply. 35ma plate current per module x 8= .28 x 300v for another 84 Watts. That was just too much heat for the inadequate cooling of the original studio. Here is the schematic for the Gates SA-70 it looks similar to the CA-70 without a part by part comparison it just had more modern 50's tubes I believe. I racked a couple of these up several years ago for a client. They were designed for AM broadcast and I didn't think they quite had the fidelity of the RCA or the Redd 47. I thought the low end was a bit lacking compared to the RCA, Redd 47 plus the Altec's and I did re-cap the Gates modules. My sense is because they were meant for radio announcers the let the low end roll out a bit early than if you were recording music. I think the transformers were not quite as good as the Altec, Collins and original Western Electric transformers but I never compared them side by side. We are clearing out my storage room today and tomorrow so all the spare microphone headgrills, shockmounts etc will be moving over to our new facility. I will finally be able to get to my boxes of old tubes so I will make a list of what old audio tubes I have there. Cheers, Dave Well there's one. Plus any parallel between CA-70 and SA-70.

aamicrophones, that's my handwriting on that schematic and my scan. The one's you racked must have been broken, they actually have a low frequency boost around 30 like a tape head bump. I've restored about 30 of them over the last 20 years, and they always have pretty extended response, generally more hi-fi than the dozen+ RCA's I have from all eras. Glance at some notes tells me -1dB points of 10Hz and 25kHz on the last set I did. If you read the Coil commentary, they are building almost exactly the same thing, same tubes, etc, just modifying the feedback path to create EQ options.
