Not sure if my PM made it but I’d be interested in the 3101-2216 switch(es). Thanks for making these parts available!

hi
do you still have these parts.
I am looking for (1) 1855-0410 fet transistor and (1) 1854-0009 or cross referenced.
Thanks
Bob

Sorry Bob, I'm not sure why I didn't get a notification of someone replying in this thread. The answer is yes to 1855-0410, I have 9 of them new in packaging. I don't have the other, unfortunately, and I don't have a X-ref for it either to check the generic numbers. I will shoot you a PM.

I didn't get a notification for you either, so I'm glad you PM'd. Your part should be arriving soon.

I hope everyone is doing well amid this coronavirus pandemic.

I will not be able to send out any international shipments in the near future until things are under control (sorry), but for the forum members in the USA, I can still ship things out via USPS Priority and First Class mail from my home. Being locked up in our houses may be a great time to fix up that old equipment!

I have an HP-5345A with supposedly a faulty front panel. My manual only covers operation, not maintenance. Consequently, I don't have a part number. Can you help me with a front panel, or at least a part number, please?

I'm sorry, but without a part number, I won't be able to help you. Perhaps search some more for a parts list, or maybe someone here can chime in to help you determine the number.

I need a 150-0047-00

it's a tiny thing, seems silly to ship just that, I'm going to look around and see if I need anything else also

Thanks for your interest. I have 4 new lamps available to ship immediately. Your country is not showing up for some reason, but if you are outside the USA, I will not be able ship these until the government lifts the "stay-at-home" order. I will private message a quote.

Hi
I just found this post and would like to know if you still have an H.P. part 1855-0410 fet .

Thanks for your inquiry Bob. Yes, I have 9 new ones and 2 used available. I will send you a PM discussing ordering procedure.

I just received a parcel with a lot of great goodies from Mark. Very easy process, great prices, great discounts and there are tons of useful stuff still there.

Just a reminder: the USPS took quite some time to deliver due to weather (similar to the other thread about Mouser).

bitseeker · « **Reply #136 on:** March 18, 2021, 02:08:59 am »

I must say I'm impressed with cycle_collector's perseverance to continue making these parts available rather than dumping them and running away screaming. This process started back in 2017!

Thanks for the kind words! You folks are a pleasure to work with. I'm not trying to make big bucks here, mostly just trying to get compensated for my time and effort in getting these parts shipped out. And yes, still lots of parts left for those restoration projects.

P.S. I think USPS has things back on track lately so no worries there anymore, luckily.

Wow, 2017... time sure does fly!!! Sometimes I ask if it's all worth it, but then I think about that guy with a vital old motorcycle part I need that ends up listing it on ebay instead of tossing it. Even after 5 years, I would still find it extremely hard to toss out all this good stuff. But if the right buyer came along to take the whole lot off my hands and get it to people that need it, I would give them a great deal.

I met some nice folks along the way and hope to meet a few more before it's all over.

HP 1854-0019?

HP 1854-0019?

Hi Dave. Normally my inventory is NOS, but in this case, I have one used transistor in a bag. The bin, however, is showing an alternate number of 2N3859 and it appears those are readily available on ebay.

If you are in the USA and want this used one, PM me. It's yours for the cost of shipping (probably $1 in a first class envelope)

Dave Wise · « **Reply #141 on:** April 06, 2023, 06:31:14 pm »

Thank you CC, but I need two. Thanks for the 2N3859 ref, I hadn't heard that before. Is it typed or a scribble? One of the UK Vintage Radio Forum cross-refs says Selected 2N2369, or (unselected) 2N2368, so we can guess that the 2N2369 was selected for low beta.

2N2369 is available from Central Semi, but if you think the original HP is selected or would be better I have some (used) in my small hoard of scrap HP boards. I can desolder two and mail them if you like, just PM me. The leads will be a bit short, but should be usable as replacements in HP-ware.

Dave Wise · « **Reply #143 on:** April 06, 2023, 09:13:21 pm »

BDunham, I'll keep your kind offer in my back pocket if experimenting with what I have lying around falls flat.

I don't think it's a very demanding application - I want to add the "Restore Signal" function to my low-serial-number 8443A Tracking Generator. Normally it builds the output signal starting with a 3MHz crystal oscillator, mixing it with the various oscillators in the spectrum analyzer. Restore Signal turns off the crystal and substitutes the 3MHz IF signal from the spectrum analyzer, so the 8443 puts out a strong, levelled wave at whatever frequency is coming in through the SA's passband. To add this feature we need to amplify then limit the 3MHz IF signal to drive the mixer. HP did this with a cascode then an emitter follower then a differential pair. One diff pair collector goes to the diode ring modulator in parallel with the disabled crystal oscillator output. The cascode and emitter follower are HP's favorite NPN, 1854-0071, while the diff pair is 1854-0019. Since we're only running at 3MHz, I figure the important characteristics are Cob, gain, and power output, and we don't actually need hundreds of megahertz Ft even though we get that too.

Hello,
I am looking for several IC 1820-0286. Can you help ? Thank you.

David Aurora · « **Reply #145 on:** April 07, 2023, 09:18:16 am »

How on earth did I miss this thread until now??

I'm after a slide switch, HP 3101-0803, though I feel like that part number may be for the whole multi-button assembly and all I really need is enough pieces of a similar switch to cobble something together from.

Here's a picture of the whole assembly, the slide switch second from the top is missing the plastic wafer thing and contacts. It basically got eaten by leaking batteries before I owned this 419A, and after a good cleanup that was the only lasting damage, I recall having it fully working with a couple crocodile clips for that section but that wasn't a long term solution obviously, just a test setup. Any similar parts to the other ones would be enough to get this back in action after it's sat on a shelf for the past 2 years or so 😂

If you've got anything that I might be able to shoehorn in there I'd really appreciate it!

Sorry for the delay, for some reason I don't get notifications when someone replies to this thread anymore.

Also sorry to say I don't have the part you seek. Good luck hunting!

Sorry for the delayed response... my alerts aren't coming through for this thread anymore.

I do not have any switches like that and I hope you can find them somewhere.

PM reply sent. I have one for you, but shipping to Australia is rather expensive. Reply via the PM. Thanks.
