Tube Preamp - Bottlehead Foreplay with Upgrades -

Posts: 2,419
In my newly beginning quest to move some hoarder gear, make the Missus a little happier, and frankly, pay for a new purchase without sleeping in the dog house next quarter - I offer up this Bottlehead Foreplay. I'm thinking $175 pickup WDC / NJ area (Dec 22nd - Jan 1st) or $195 shipped CONUS - Polkie price only please. I will include some nice tubes to get you rolling (see what I did there) as well as the stock ones it came with, (which I would not recommend). Also, I have a small swatch of Dynamat Extreme I always intended to put to use on it, but never did, I'll also include that.
I purchased as a stop-gap when I temporarily fried my Dodd MLP and a few others I have tried along the way. I have to say, its a fine and very serviceable tube preamp. It uses cheap and plentiful 12Au7's (a pair) and responds well to rolling in my experience. It already has several of the most popular upgrades for this particular unit installed including, tube preheat, cap upgrades, and the stepped attenuator upgrade. (C4s, Anticipation, and I can't remember the other). I do have the paperwork on the upgrades, and I think even the original assembly instructions as well.
In the interest of full disclosure, I was planning to change the stepped attenuator to a nice Alps pot somewhere along the way, as changing volume while running a signal results in a scratchy burst of sound between steps that I just didn't dig. Other than that, this is a surprisingly good unit and punches WAY above it's weight. For photos and my initial thoughts - here is my intro piece on the forum:

No Schiit! -
Is your Dodd MLP still as listed in your sig ("on the bench" w/Charlie)? I'm going to contact Charlie Cocci after the holidays. Is that who is working on your pre? Thanks!
-
So if I have a dac it would have to out of the dac to this unit and then to my amp?

Thanks all - if you can pickup, I'll throw in a free set of Monitor 4's - in the original boxes, (non-Peerless), I don't have photos, because I've never used them!

Yes, still with Charlie, FWIW, I've found that he actually doesn't like working on Gary's stuff... at all. Since he made me the MFA I haven't been pushing things, because I'm not in a hurry, but I have just started the conversations again to get it going.

Wow, even better deal. Throw in an 8 by 10 glossy of Russ and Ivan making out at the last Polkfest and you'll get some takers.

What tubes are you shipping with it?
Hey skip, i have the original Soviet ones that came with it, I liked RCA Cleartops, so I'll include a set of those, and I'm thinking a set of 5814a's which are also nice, as I recall they are also RCA's, but don't quote me. Who know's maybe more!

I've met Ivan. Russ must've been drunk because Ivan is surely not Russ's type. The car doesn't tilt to one side when Ivan gets in.
Thanks Skipper's......... I think -

Good to know (since he's touted as the "go to guy" for Gary's designs). I will most likely just gut my MLP and build a grounded grid circuit in the case. Thanks!
Sorry for the detour....
Yeah, someone should grab this quick. -
Yea, maybe I caught him on a couple bad days, YMMV, but it was not my impression he enjoyed being the go to, despite the fact that is exactly how i found him to LOL.VA HT HK AVR20II, Sony S9000ES CD/DVD/SACD, Polk Audio RC80i / Polk Audio CSi3, 60" Panasonic Plasma, Nordost / Signal Cable A2 / Wireworld / Pangea / Magic Power

So glad. I have been quite tempted, but have a Quickie that is still burning in after upgrades and an Eastern Electric Minimax pre that I need to listen to more. Glad it is moving on to a new home.
