Re: Technics Sp10 Woes

Not wishing to derail Wolfgang's thread, with the scarcity of AC filament bulbs in favour of low energy LEDs etc. I have wondered about using an LED possibly with a small Arduino to control it. I haven't thought about it in any detail but I reckon it should be doable, but I'd be interested in how yo...

Re: Question re grounding

Yes, true, I was a bit sloppy. I've never had a trafo with separate secondaries to be able to try this. But certainly giving the driver stage a whole separate PS (trafo, rectifiers, LC filter) was a notable improvement over a shared PS when I tried it with the GM70 amp. Whether it's better than sepa...

Re: Question re grounding

Yeah, if I had three separate PSs the only change I would consider in your situation is three separate power trafos for galvanic isolation. Which may or may not be better. But if you're going for a single PS then I'd use one rectifier, probably a single LC, and then further LCs to each stage. But yo...

Re: Nothing In Particular

I remember going to a pub in The Dales not long after I went veggie, over 20 years ago. We've been going there over 30 years and I knew the menu was based on cow and pig, and gingerly asked if they might be able to rustle something up for me as I was now veggie. The landlord had a think and suggeste...

Yeah, especially in sport mode at lower speeds.

Re: Nothing In Particular

1800cc. They used to be 1500 but were underpowered. The 1800 engine with the improved hybrid system now is a nice balance. Never going to be a petrolhead's dream though.

Re: Nothing In Particular

Same company AFAIK so it'll be the same hybrid system I'd guess.

Yes the Lexus system is much the same from what I read.
I imagine they're the same hybrid plant, maybe with a tweak for the model.

Re: Nothing In Particular

I also spend a goodly amount of time in stop start traffic, which with a light foot I can run purely on batteries. Not sure it'll work quite like that. Yes the hybrid plant switches off when you come to a halt, and mine will run on the battery upto about 25mph if I'm light on the accelerator. But t...

Re: Nothing In Particular

Looks even better when I subtract my £250 a month fuel bill. How do charging costs compare? I've no idea. Guessing, if a 60Kwh battery will give you 250 miles my 80 mile trip would use 20kwh. Say a night rate of 11p per kwH, that means a days commute will cost £2.20 or say £45 a month. Currently I ...

Re: Nothing In Particular

I can see the point of a plug in hybrid if 90% of your journeys fit in the battery, but not like both of us where most of the day is outside the battery range. You are just using petrol to carry some discharged batteries around. I can see that, but the hybrid system recharges the batteries during t...

Re: Nothing In Particular

Doing some digging, it appears Lexus battery faults are very rare even in older cars My brother bought a Lexus SUV type hybrid a few years ago. It wasn't new but he had a problem with the hybrid system out of warranty (I don't remember exactly what now) and feared a big bill. Lexus sorted it free o...

Re: GM70 PP

Looking at the HT PS again Stephen, it kind of looks like you're using connectors to connect the trafo and first choke to the rest of the filter. Have I interpreted that correctly?

2120V CT is an interesting voltage!
