Thanks for the replies. I didn’t realise Cayin had a German site. I have used Langrex once and they seem very good. Watford valves seem to have a good reputation also, I was recommended some Radio Technique 12AU7 half plate by the guy there, might be worth a shot.

I think the stock EH 6V6 seem pretty good, although I not had much chance to run them for many hours. I am thinking of getting a spare rectifier but there doesn’t appear to be any UK stock, does anyone know a good source for these.

Many thanks for your message. I hope the replacement amp works out. I guess I got a little unlucky with the first one, it was getting very frustrating as I could tell it was a great amp but could not get to enjoy it properly. The new one is definitely sounding better, even though the old one...

I received a replacement matched Gold Lion today to replace the one that went bad in the old amp. Will stick with these for a while but no doubt will be tempted by some NOS tubes moving forward. Will run the amp for a while to make sure all is good. Have got some Reflektor 6V6 as spares but...

I am pleased to say that my dealer has been very helpful following the need to return my amp for a second time & has now sent me the brand new amp. What I had not realised is even when the old amp appeared to be working fine it was not actually sounding as good as it should. The replacement...

I have had a couple of good second hand purchases, best one was a Garrard 401 for £1 at a car boot sale. My Icon HP8 was second hand and that was always ok.

It’s fair comment, buying a demo tube amp was probably not the best choice in hindsight. I have bought ex demo kit before and been happy with it. Hopefully the new amp proves reliable. May even sound a little better. Ever before the tubes went bad I thought the right channel sounded slightly...

Hopefully all will be ok with the new amp, I will run the stock tubes for a while before buying anymore, already ruined two pairs of tubes + the original stock tubes. I was getting seriously frustrated, not good on my wallet either. Not had confirmation of when I will receive it but at least I...

I am very glad to report that my dealer has now agreed to supply a brand new amp. I have had to pay an additional fee on the original demo price but this is ok with me if it means getting a brand new one. Still not sure if I will stay with tube long term yet, although I have found a local...

I would be using HE1000 Stealth so quite easy to drive

I appreciate everyone’s help & input on here. Will let you know how things progress. Just out of interest has anyone had experience with the Pathos Aurium, got a chance to pick up a used one which could serve as an alternative whilst my Cayin is being repaired

I am not clear what facility my dealer has for repair, hopefully any work can be done in the UK, save on shipping times. I will know more in the course of time.

The amp has just been picked up by the courier to go back to the dealer, hopefully will get some progress on it soon. I really like the Cayin but probably not the best choice for someone with a one amp setup, I will put it up for sale once I get it working fully, started to look at my other...

The amp is being collected by my dealer today, will hopefully be able to pinpoint the source of the problem, will let you know what the outcome is

Thank you for your message, I understand what you’re saying. Unfortunately whilst I understand why the repair times can be longer due to the logistics it’s not something that ultimately will work for me in the long term. I don’t have spare amplifiers & to be potentially with out for months is a...
