If the inspiration is nostalgia, then I say go with the vintage pair. Then again, there are some good deals on RP600Ms; they are probably “better” than the old KG1.2s.

I have a single HII mounted as you describe, it’s used as a Center in a 5.1.2 capable system, and it sounds good no issues. Admittedly, it’s not enabled for critical listening, but with movies, games, & multi-channel music; it serves that purpose well. I say go for it. Be careful getting them up there, they are cumbersome.

No clue on repair options. I didn’t even know they made receivers, I’ve never seen one. Good luck, I imagine it’s going to be difficult to even find a “donor unit”. Maybe find a working one and keep your old one as the “donor”? It seems that a lot of the newer old stuff, is less repairable than the old stuff.

As far as I know, it is not. I was a big fan of his tung oil varnish. I used the last I had on my Raw Birch, LaScalas.

I am fortunate enough to own both H1s (1980) and the H1.5s(‘83) (Also a single H2). When I got the ‘83s I’d owned the ‘80 H1s for several years. I immediately thought the ‘83s, sounded much better than the ‘80s, fuller bass, & smoother high end. I just assumed that it was either in my head, or a slight manufacturing variance. I.e. the ‘80s may have been a “post-lunch break” build. It wasn’t until I decided that I should open up the ‘83s and check & tighten the connections that I realized what I had; the H1.5s. It’s only my opinion, but I thought they sounded better, even before I knew there was a difference. I’ve never heard a pair of HIIs in my music room, only the one which I use as a center when running in 5.1.2. Although, my son-in-law has HIIs and I’d guess their sound is closer to my 1.5s You’ve got a nice pair of speakers, I personally prefer the older Birch plywood cabinets over the MDF, for whatever that’s worth.

The T18 will work well with your Heresys. I’ve also got a pair of 1.5s, and it is a good match for them.

Excellent! Which one are you building? I’ve not purchased any BB since the pandemic, it wasn’t cheap even then. I hope it goes well, I can’t imagine being disappointed with the results. We had the kids back home this weekend, and had a Disney movie on for the Grandkid, and my son even commented on the bass output of the little T18 in the family room. Keep us posted on your progress. Read & re-read the plans before you begin. You can’t have too many clamps! Keep things square & follow the plan!There are a few folks on here who are ace builders and they’ve been a great help to me. I’ve been wanting to build a THTLP, just because it would be a better fit in my music room, but that may be a post-retirement project. Good luck on your build. I’m looking forward to seeing your progress.

I’ve just had my M-1.0t refurbished & upgraded, also recently had my Sunfire Cinema Grand repaired, after a power surge. I listen to his amps most every day. I hope he’s doing ok.

This is the T18 build. They are great projects, if you are reasonably handy.Buy the plans & follow Bill’s instructions to the letter and you’ll get good results. If you decide to go this route,there are some folks here that are ace builders, and great resources. Good luck, I’m happy to offer any advice that I can. https://community.klipsch.com/index.php?/topic/182249-t18-subwoofer-project/

I found the thread, for my Table Tuba build. It turned into my “Pandemic Project, as I’d just finished gathering parts before the world shut down. it documents the whole build.

Actually, I’ve documented the two I’ve built in threads on this forum. I’ll find the links to those threads. Here’s a pic of the one that probably would suit your Heresys fairly well, it’s the T18.

My son-in-law is running Heresy iis with an SB2000, and it sounds great. In a larger space than yours, but still a good match. I’m a big believer in DIY subs, if you are up to a bit of effort the results are quite rewarding. I’ve built a couple of Bill Fitzmaurice’s designs, and they are great with Klipsch speakers. https://billfitzmaurice.info

The 1.5t MKII OPT II, has been re-installed is doing well. The “Thump”, has been eliminated, best of all the ceiling fan can be turned on & off without terrorizing our dog, and everyone else in the house. So, a win there for sure. Full disclosure, it’s probably overkill for the family room system, which is mostly TV/Movies 30% usually 5.1.2; with the Carver powering the L&R RP-280Fs. So, it rarely gets the chance to “Rock”. First impressions upon re-install were, that it was a bit harsh on the high end, this has either settled out after several days, or I’ve just grown accustomed to it(maybe it’s just the RP-280Fs that are “harsh”). It now has that usual increase in richness and soundstage that I’ve come to expect with external amplification, even just two channels, frees up the Denon to power everything else better. The Center ch dialogue is clearer without the load of the L&R. For 2.1 music, usually streamed through AppleTV, it is effortlessly reaching insane volume levels, and sounding good. If I get ambitious I’d like to hear it how it sounds with the La Scalas. Moving heavy things around, and re-wiring, is not on my agenda today. if you have one these old Carver amps, check with Nelion Audio, and let Greg work his magic, It’s worth it. Money well spent in my opinion.

Updating the story of this Sunfire Cinema Grand Amp. Just in case anyone needs one of these units repaired, and would like a solid repair/refurb service recommendation. You will be well advised to check out Nelionaudio.com Greg is aces. Once back in regular use, the amp performed flawlessly for months. Long story shortened; the electrical transformer that feeds our house, shorted out due to vines growing up the pole, and into the wiring. Only one piece of equipment in the house was damaged during the rather spectacular “event”. Yep, you guessed it. So back it went, to Greg at Nelion audio, after an extensive repair, at a more than fair cost, it’s once again back in service, and as good as new. I’ve recently sent my Carver M-1.0T to them for refurbishment & upgrade to their M-1.0T mkII opt002 specs, which ups the power from 200 watts to 460, and claims to silence the power-on, “thump” that these amps are known for. They quickly performed the work, and returned the amp. I’ve not had the chance to get it back into the family room system, but my expectations are high. I’ll follow up once I’ve put everything back in place.

Why not find a plate amp, that closely matches the dimensions and wattage, and replace your failed amp with that?You might have to shim or trim to get a good fit, but that’s what I’d do. Surely Parts Express has something close, if not an exact replacement.
