[Germany/EU] WTB: Alps RK27 20K dual volume POT (20KAX2)

I'm chasing an Alps pot for a Creek integrated amp I just picked up. Obviously I'd prefer it to be genuine but will consider clones. Please let me know if you have one you're willing to part with! Thanks for any help :)

WTS/WTT [USA - WI] Mark Audio Super Pensil Cabinets $50 obo

https://preview.redd.it/ym3jlytakju61.png?width=997&format=png&auto=webp&s=033a10090fa0db0903e40668f5020d3b0ed2f276

I recently built the 12p-sized frugal horn and removed the drivers, hook up wire, and terminal cups from these cabinets. The 12p sounds great in this cabinet, it was just time to build something new and I had the room for the larger FH-type enclosure. Rather than store them (they're big), I'd like to see them go to someone who can enjoy them.

The top and baffle are a butcher block and the sides/rear are a stained plywood. There's a little checking here and there and the cabinets could use a quick sand and fresh coat of poly, but they're structurally rock solid.

You can find approximate dimensions here: http://www.frugal-phile.com/boxlib/pensils/Pensil-Series-set-100711.pdf

Would trade for tubes, amplifier parts, woodworking tools (power or hand tools), bench equipment (power supplies, etc). They are located near Milwaukee. EDIT: THESE ARE GONE

WTB [CAN] dual 8" 4 ohm or 10 or 12" DVC sub & pair of 4" full range drivers

I'm sure some of you out there have bought drivers with good intentions and never followed through with a project/build.

SUB - I'm looking for a Preferably 4ohm DVC sub 10 or 12" - something that would be good for small HT or PC gaming setup & music listening. I'm using an MTX terminator right now but I'd rather have something more suited for real music, and would work well with a 80-100w amp (I'm using a cheap class d amp that is working quite well 2 ohms). Drivers i've been considering: Dual 8" Dayton SD215A-88, 10" Dayton SD270A-88 or a single 4 ohm dvc 12".

FULL RANGE: I have some nice little boxes already built - had some cheap 4' car coaxials in it but they sound crappy. I'd like to try a small single driver full range build - something like Dayton PC105, Tang Band W4-2142 4", Tang band W4-1337SDF or anything similar that can give a wide response range and quality sound. They are for rear surrounds for gaming and multi-channel music.

I would also consider a 2 way setup if crossovers were included...let me know what you have!

[WTS] [US-PA] Overnight Sensations DIY Speaker Kit from Parts Express- $70

My wonderful wife got me (at my request) the Overnight Sensations DIY speaker kit from Parts Express. Well, here we are, 2 years later, and I have yet to build these things. So, I think it's time to let them go to someone who is lwil assemble them and enjoy them.

I like just outside of Philadelphia, PA and am looking for a local pickup. Paypal is fine, but since we're doing local pickup I'd prefer cash. I have done NOTHING with this kit, other than open the box it came in and make sure all the parts were there. Totally brand new. Been sitting in the corner of my family room for the last 2 years.

[WTT] Looking for 211 tubes, have power tubes to trade.

Title says it all! I have 4x 803s, 4x 809s, 2x 811A, 1x 811, and about 8x 1625s, 1x T-55, and 2x 866A. All NOS, about half in boxes (the others boxes literally fell apart in my hands). Most are WWII vintage JAN models. Looking for NOS 211/VT-4-C in trade. Let's work out a deal!

[USA - WA] WTS Speedster speaker kit $200 + shipping OR WTB finished Speedster cabinets

SOLD

I bought a Speedster speaker kit a while ago, but lost my work area before I was able to build the cabinets. Either looking for someone to build fully finished cabinets for me (please PM with estimate), or to sell my two-speaker kit for $200 + shipping to you. I'll also include high quality gold binding posts, damping material, and speaker wire. The crossovers have been fully assembled and all components are tested and working.

I also have an Audioengine N22 amp that I can include for an additional $70. From my sound tests, it was sufficiently powerful and sounded great (well, as great as it can sound without cabinets at least...)

Pictures are here.

I take PayPal Goods & Services payment only.

WTB[USA-IL] Matched Pair 01A tubes

I'm ok with pretty much any brand, as long as the two tubes are from the same brand and test well. I really really want them to be globe shaped, and am looking to spend about 50 USD, maybe 60 MAX shipped. Preferably longish pins, I've seen some out there with really short pins, they should fit in a standard UX4 socket. I can pay with paypal(as long as it's not friend and family) or use credit card, whichever is easier.

Please practice safe swapping

These buy/sell/trade threads are for private transactions. We provide these forums for the convenience of our community members, but the moderators make no warranty nor assume any responsibility for transactions here. We do not vet any members (though there are karma and account age minimums). Use of /r/diyaudioswap is at your own risk. All Reddiquette rules about conduct apply and will be enforced.

###Please observe these post requirements:

  • All post titles must contain WTT, WTS, or WTB as well as link flair (assigned after submitting)
  • All post titles must contain location in the format [USA - State], [Canada - Province], or [Country]
  • If for sale, title must include price
  • If trading for something specific, keep post titles concise (include more information in the body of the post if needed)
  • All for sale or trade posts must include a picture of the item with handwritten username and date
  • No links to outside listings

###Good practices for buyers:

  • Use PayPal and do not send money as a "gift"
  • Ask for tracking information
  • If you are in a hurry to receive something, please be clear about this to the seller
  • Be patient; some shipments (especially international) may take a while to arrive
  • If you positively cannot sign for a package, please be clear about this to the seller

###Good practices for sellers:

  • Take pictures of the packing process
  • Provide information on the original design/schematic as well as any changes you've made (if applicable)
  • Be careful with international shipping
  • If you will not be able to ship immediately, please be clear about this to the buyer
  • If you plan to require a signature, please be clear about this to the buyer
  • Mark things as SOLD or TRADED after the transaction

###Both parties:

  • Research the other person's account; are they active members in other DIY or audio communities?
  • Research the design/parts that are for trade/sale; be sure you understand exactly what you're getting.
  • Is the other person asking you to do something strange like re-wire money, fudge the claimed value, etc? Be careful.

Please buy, sell, and trade safely out there folks. There are a lot of great people in our hobby, but there are dishonest ones too.
