Bush TV22 Service Instructions for Mk2 chassis (not Trader sheet)
Hi
I have looked for the original Bush TV22 (and TV24, I believe) service instructions covering the Mk2 version of the set, but can't find this anywhere. I only have a low-res version for the Mk1 version. Does anyone have this, or know where I can find it? I have the proper Trader sheet (for the Mk2 chassis) but would really like to have Bush's original service instructions as the trader sheet misses some information, like resistor tolerances and power ratings. Many thanks Helder |

Hi Helder,
I think you'll find it on Jonz site. http://www.thevalvepage.com/tvmanu/bush/bush.htm Scroll to the bottom of the page. Peter |

I think you will find Jonz site only lists a Bush service manual for a TV 22A which uses a PL81 line output valve though the RF board with the EF80 valves should be the same. I have repaired two TV22 mk2 sets and still have not come across a Bush specific manual for these sets. I just used the Trader service sheet.

Re: Bush TV22 Service Instructions for Mk2 chassis (not Trader sheet)
There was a TV22 service instructions supplement published Dec 1952. Not sure if this is what you require. the issue 'B' receiver valve line up is V1, V2, V3, V4, V6, V7 and V8 are type EF80 with V5 and V9 being type EB91. Issue 'B' main deck has V1 PL33, V2 and V3 ECL80, V4 PL38. The pages are foolscap size, so would need scanning as A3. PM me your email if it seems the correct info.
