Sure! The base kit was $395 + shipping. Sides, bottom and extra tubes were $25 more; I went ahead and got them and am still finishing the sides (the picture I attached shows them stained only - they are nicely cut and routed. Nice oak pieces. I'm glad I got them - still have to finish and attach them.). It comes in many colors - I picked black. I'm playing my spud through Heresy I's. So far my source has been a Fiio High-Res player (with FLAC files) and I have a small headphone/pre-amp in between the player and the new spud. I think the spud needs a good strong input signal. I found that building it did take effort and some thought. It was fun; I didn't rush and I worked on it on-and-off for the entire week between Christmas and New Years. It was a nice break from my full-time job. I even labeled the "B+ power supply connection" and "Screen Grid bias connection" (ha ha I just felt like labeling those) I feel a sense of accomplishment and it's rewarding to listen now, having had a role in creating the amp. Pretty cool to be listening to the parts I soldered and stripped and assembled/oriented correctly/made sure were well-grounded etc. and it even sounds awesome too! I understand that there used to be a forum dedicated to discussing this amp and related mods. It was at a place called Hawthorne Audio that went out of business unfortunately. I think Jerry is trying to recover those discussions which would be very cool if possible. My impression is that this amp really is a labor of love for Jerry and he was great to work with. Anyway to me, all things considered, it was really worth it.

Hello, I built the spud kit referenced above over Christmas break. It was a blast. After about 10 hours of listening now it is really breaking in nicely and sounds great. I contacted Jerry several times with questions and he was extremely helpful. The directions and pictures were excellent. I feel that i learned a lot from this and enjoyed the challenge of trying to build it as neatly as I could. I highly recommend the spud kit. Thanks Maynard for your post which led me to this project.

Those are very cool. I love the ruggedness of them.

Thanks Bossman. I sent a message. I'm very interested to learn how you adapted your Type E for the D250X (also 8 ohms).

Thanks guys. I really don't have any right to expect this kind of help. It's the D250PH. Very inexpensive but it gets into the midrange frequencies very well so I'm giving it a try.

Sure. Interior dimensions for the cabinets: 11.25 W 12.75 D 42 H just under 3.5 cubic feet interior. I'll attach a picture. I built them over the summer out of baltic birch - found a nice source for it and it makes them look Klipsch-like. The two ports are supposed to tune them to about 32 Hz. The woofers are 2-8” Dayton 295-377 4 ohm. I intend to wire them in series to create an 8-ohm load. Hoping to get them to sound as good as possible and I like the idea of incorporating the T2As if I can. Thanks again.

I also found the tables below in an old post . . . instead of 256 ohms, I guess I'm looking for 128 ohms for Tap 1 . . . to maintain 700 Hz crossover frequency. But maybe I'm only going to get -6 db of attenuation unless something else is done in addition. (The woofers I picked for my project are Sensitivity = 93.8 dB 2.83V/1m, so it would seem that I need the whole -12db) t2a at 16 ohm driver tap attn multi impedance 4 -3 2x 32 3 -6 4x 64 2 -9 8x 128 1 -12 16x 256 t2a at 8 ohm driver tap attn multi impedance 4 -1.5 2x 16 3 -3 4x 32 2 -4.5 8x 64 1 -6 16x 128 I appreciate any advice very much.

Thanks Dean! I was hoping you'd see this question. Here are the specs of the driver that I'd like to use with this Type E network/T2As: Power handling: 75 watts RMS with recommended crossover of 500 Hz, 12 dB/octave slope • VCdia: 2" • Impedance: 8 ohms • Frequency response: 400-8,000 Hz • SPL: 107 dB 2.83V/1m Also, I found a very relevant post that you wrote 10 yrs ago to explain why 11 ohms swamping resistor and 21uF capacitor: "the goal is to create a somewhat constant impedance, with low pass and high pass sections somewhat equal in impedance. The design assumes the K-22-E is 11 ohms at the crossover frequency (700Hz). To get the matching high pass section, and the proper resistor value for the autoformer -- we need to know the reflected impedance with the tap we are going to use. In this case, it's tap 1, and we'll go with 256 ohms (even though it's actually a little lower than that). At this point we bang on our resistor calculator until we find the value that gives us our closest match to the impedance of our low pass section at the crossover point. Using the calculator, we discover that if we parallel an 11 ohm resistor with 256 ohms -- we come up with 10.54 ohms. 11 ohms is close enough here, and we strap it across taps 5 and 0. Now we need the correct cap value for 11 ohms at 700Hz. That value is roughly 21uF. This design presents a benign, stable load to the amp --"

ha ha, thanks! These were stock Type E's, so here is what I did to end up at the diagram above (there is also a lot of discussion about this mod in other threads on this forum): - The woofer inductor was changed from 2.5mH to 2.2mH. I splurged on a nice ERSE inductor after a recommendation from Bruce. - The Squawker taps were changed from 2 to 1. - Tweeter connections were changed from tap 3 to 2. - The 2uF cap in front of the autoformer was changed to 21uF (I used 2 caps in parallel to get to 21uF) - An 11-ohm resistor was strapped across 0 & 5 taps.

Hello, I have a question, please! About 4 mos. ago, I got brave and made changes to my Type E crossovers (schematic attached) based on what I learned on this forum, with help from several of you, and it worked out very well - holy cow, they sound tremendous in my Heresy's. I am still amazed 4 months later after much listening. I am glad I did it and I think you guys are the best Klipsch experts out there. So . . . I want to use the same modified Type E network in another horn-loaded 3-way application which has the same 700/6000 crossover frequencies. The squawker that I'm planning to use is in my new speakers is rated 8 ohms . . . I know that the K-55-V is rated at 16 ohms (however K-55-V squawkers that sound awesome with the modified Type E network test at 11 ohms with a multi-meter, disconnected). My question is: should I change something in this modified Type E network for an 8-ohm squawker? If so, what should I try? Seems like the 21uF cap or the 11 ohm resistor are what could be affected by the change of drivers from 11 ohm (or 16, or whatever a K-55-V is) to my new 8-ohm compression driver. Thanks very much for any comments. (I barely feel worthy to post on this forum so I hope you'll go easy on me.)

Hi, I chose a Nikon D3200 for my daughter last Christmas! It came bundled with both standard and telephoto lenses. It's been a great camera. Very flexible! Takes unbelievably-great photos. She's been able to use to learn about aperture and shutter speed combinations. It's fairly lightweight also. Anyway we like it a lot. (I borrow it!)

Hello. Last summer I repaired an over-excursion damaged K-22-E with the Parts Express glue mentioned above (340-076). While this glue looks like wood glue, it dries clear and "rubbery" and stays somewhat flexible. I thought it made a good repair - certainly glued the fibers down in my case - but it's far from invisible. Anyway I decided to upgrade to new woofers. Just thought this might help others if they are deciding between glues. Good luck!

I have the debut carbon and like it a lot. The anti-skate mechanism is kind of interesting - small weight on what looks like fishing line, run through a wire ring. It's manual so you have to do everything but I don't mind that. good luck!

"cap them" means, simply, replace the 40-yr old capacitors that are in your crossovers with new ones that will bring everything back into spec. I did a lot of reading about my Heresy crossovers and it's commonly believed that capacitors drift out of spec over time and need to be replaced. It was an easy job if you are able to solder. I used these caps in my Heresy I Type Es as a low-cost alternative: Dayton Audio PMPC-2.0 2.0uF 250V Precision Audio Capacitor https://www.parts-express.com/dayton-audio-pmpc-20-20uf-250v-precision-audio-capacitor--027-214 Model: PMPC-2.0|Part # 027-214 I hope that helps and good luck! That's very cool that you kept those speakers all these years.

Just for fun, in case you haven't seen it, I'll attach a brochure that I found on the Heresy I. I think this is a very cool document! It makes the point that Heresy's were not designed for low bass response (only 50 Hz) and gives a really good description of the design. I've really enjoyed having these speakers. Heresy I Flyer.pdf
