Wayne's BA 2018 linestage

When I did my smd’s I followed the advice but instead of trying to hold the smd with a toothpick etc. I took a small piece of scotch tape and taped half of it down. Tacked the exposed leg took off the tape and soldered the other 2 legs then reflowed the first one. Bob’s your uncle! Easy peasy, then clean

Thanks turion64. There seems to be a limited selection for my Stahl DDSS system which has been so effective for me in the thru-hole projects. I have this tip set on the way but nothing there that seems like a "chisel". Do I need to invest in a better iron with more flexibility for the SMD stuff? https://www.amazon.com/dp/B004D06QM4?psc=1&ref=ppx_yo2_dt_b_product_details

Investing in a good soldering station will make your building life much easier but what you have will probably work fine. Don’t spend money if you’re not serious, or crazy, about this hobby. BTW, I don’t think the tips you posted are made for your base model. Chisel, or screwdriver tips, just heat better (IMHO) but don’t spend $ just to put 8 SMDs on, especially these on the BA2018. I finally bought this one (ADS200 AccuDrive Soldering Station with TD-200, ISB Cubby & 3 Tip Bundle (120V Only) | Pace Worldwide) because it gave finer control for soldering. It was my gift to myself and it wasn’t terribly expensive (but it was not cheap by any means). You can see the two chisel tips that came with the kit. The SMD parts for the BA2018 are small, but easy. Fine diameter solder will make your life a lot easier. I’ve always used 620F (326C) for all of my work, including SMDs, and nothing ever got destroyed as long as you worked quickly. Polystyrene caps are the only exception to the temp rule that I’ve used and heat sink clips are used with soldering them.

Yup, another tried-and-true method. Lots of folk report positive outcomes using tape. Use any technique that works for you!

I'll be retiring very soon and when I have time on my hands, I may upgrade. I've never seen that one before and it will be highly considered when time. Thanks!!

Another of Wayne’s BA2018s. Incorporating Lenny’s VCU Muses board/display/remote offering - great value for $100, IMO.

it’s done in laser-cut perspex and attached to a 2mm-thick 2U blanking plate for use in a rack. I am waiting on a Faraday cage enclosing the BA2018 that one of the local metal-working concerns with an industrial punch has been promising for about a month - but the manager is family so I’m low priority.

It has two source inputs and a tape monitor. The Krell chassis in the last image is an M2X in disguise 🙃.

Fantastic build, Derek! Congratulations, attaboy, and good on ya!

One day I hope to add a 70s vintage Dokorder to my sysem; model 1140 or 1120. ... But finding a qualified servicing person will be very difficult.

Thanks, Mark. I’d have thought that you were waaay overqualified to service a Dokorder!!

The Revox in the image came in to my possession at the beginning of this year in terrible condition. I paid $150 for it and spent about $500 restoring it, with valuable help from a retired senior BBC engineer. Took months but it was a labour of love kind of project and it’s now working great - calibrated and completely rebuilt mechanically and electrically. So go for that Dokorder….
