    The Multi Amp aka Dynalo Mk2

    You could go ahead and build the SS Dynalo and rewire your Grados for balanced (that part should be easy as you should already have 4 wires). Make up some balanced to unbalanced adapters to take the 4 pin XLR you would use back to either (or both) a 3.5mm and 1/4” TRS plug. This place is all about overkill after all.

    The Multi Amp aka Dynalo Mk2

    The SS Dynalo does support SE input, but without wiring your headphones for balanced output, you would be wasting 1/2 of the amplifier sections by using a SE output. There was someone on eBay who sold a reasonably priced Dynalo (Kevin even bought one, or at least commented on it, but I don’t remember who the seller was and don’t see it now.

    DIY mini T2 Build Thread

    I've always bought mine directly from Linear...
  7. I know some of the newer and cheaper Chinese digital scopes are all the rage (Keysight, etc.) I am toying with buying a refurbed Tek 2465A, completely working, for a decent price. I know these have a proprietary IC in them, that if it fails, turns these into a doorstop (though I seem to recall this IC being available now...). Good idea or bad? For some reason, I've always wanted one of these... Flail away.

    Oscilloscope question...

    Thanks Craig! At this point, even though given the cleanliness of the scope, I'm leaning towards returning it as something doesn't feel right. I really wish I would have jumped on the other one, but it was gone. One other thing I didn't mention, but which bothered me, was the fact that when I was taking the scope to my shop in the basement, and carrying it by the handle, it seemed like the guts were moving around inside the case, almost as if a rear bracket wasn't secured, etc. I picked my 465b up and carried it in the same way, and it was solid. I asked a question about this, and the seller finally replied, 3 days later: Remove the rear cover 6 screws and fix what is loose. Nothing should be moving around. Here is the description on the one I should have bought: Offered here is a Tektronix model 2465A 350MHz 4 channel analog scope. This instrument has no options. With so much hype surrounding the Tek 24xx scopes, I will be succinct: I buy, sell and repair electronic test equipment for a living, and have for decades. I have worked on hundreds of scopes, and have all the calibration equipment service this model for some of the largest repair facilities in the country. This scope has had the power supply serviced with all small electrolytic capacitors replaced with high quality Nichicon 105c parts. A complete adjustment was performed using Tek factory equipment. This instrument didn't need any other repairs. This scope looks great and works perfectly, guaranteed. And the one I bought: For sale is a FINE working Tektronix 2465A 350Mhz Oscilloscope. Real nice condition and works great. Comes with power cord and cd with operating and service manuals. Cleaned, repaired and tested for proper operation. No start up errors. No physical damage to case or knobs. This item will be well packaged.

    Oscilloscope question...

    Thanks Craig, I was already a member of the Tek scopes Yahoo group. I signed up for its replacement (I gather) on groupsio this weekend. It wouldn’t surprise me if the seller is a member there as well. I just wanted to run this by you guys first to see what those of you with a lot of scope experience thought.

    Oscilloscope question...

    I got the 2465a and have been learning some of its features. When I was a tech in the ‘80s I’d never used one of these (they may not have been out yet), instead using 475s and 485s and 7000 series mainframe scopes. At any rate, I’m questioning whether the triggering is working correctly or not. My 465b seems to trigger better, and has a somewhat sharper display. Almost the opposite of what I was expecting. Everything on the 2465a seems to work, but I am thinking that this one should should work considerably better than my 465b. I think I can return it if I want for another 14 days or so. Maybe I’m just being a whiny little bitch Sent from my iPhone using Tapatalk

    Mouser has 500 of the PZTA06 in stock. From a quick glance, the BCP has a higher rating...

    I could probably be into trying one of those with my orthos. See if it can unseat the DynaFET... Sent from my iPhone using Tapatalk

    The link in the post from me quoted above was intended for Dynalo Minis only. Also, I never thought that stacking the amp boards like that was a good idea from a heat perspective.

    Yeah, probably. Unfortunately, unless you want to go with SMPS (or even can), the PSU is where the physics rubber meets the road, so to speak...

    I would get a 465b instead of the 465 if you can find one.

    New HBO series True Detective

    Just watched the 1st 2 episodes of this and it seems pretty good so far. Stars Matthew McConaughey and Woody Harrelson as a pair of Louisiana detectives trying to solve a serial killer case.
